L2VPN Interworking

Interworking is a transforming function that is required to interconnect two heterogeneous attachment circuits (ACs). Several types of interworking functions exist. The function that is used would depend on the type of ACs being used, the type of data being carried, and the level of functionality required. The two main Layer 2 Virtual Private Network (L2VPN) interworking functions supported in Cisco IOS XE software are bridged and routed interworking.

Layer 2 (L2) transport over multiprotocol label switching (MPLS) and IP already exists for like-to-like ACs, such as Ethernet-to-Ethernet or Point-to-Point Protocol (PPP)-to-PPP. L2VPN Interworking builds on this functionality by allowing disparate ACs to be connected. An interworking function facilitates the translation between different L2 encapsulations.

Restrictions for L2VPN Interworking

General Restrictions for L2VPN Interworking

This section lists general restrictions that apply to L2VPN interworking. Other restrictions that are platform-specific or device-specific are listed in the following sections.

  • MTU configured on the AC should not exceed the MTU in the core of the network because fragmentation is not supported.
  • The interworking type on one provider edge (PE) router must match the interworking type on the peer PE router.
  • IP interworking with native VLANs is not supported.
  • Ethernet VLAN (Type 4) interworking is not supported.
  • Only the following quality of service (QoS) features are supported with L2VPN interworking:
    • Static IP type of service (ToS) or MPLS experimental bit (EXP) setting in tunnel header
    • One-to-one mapping of VLAN priority bits to MPLS EXP bits

Restrictions for Routed Interworking

Routed interworking has the following restrictions:

  • Multipoint Frame Relay (FR) is not supported.
  • QoS classification on IP ToS, DSCP and other IP header fields is not supported.
  • Security access control list (ACL) and other features based on IP header fields parsing are not supported.
  • In routed mode, only one customer edge (CE) router can be attached to an Ethernet PE router.
  • There must be a one-to-one relationship between an AC and the pseudowire. Point-to-multipoint or multipoint-to-point configurations are not supported.
  • You must configure routing protocols for point-to-point operation on the CE routers when configuring an Ethernet to non-Ethernet setup.
  • In the IP interworking mode, the IPv4 (0800) translation is supported. The PE router captures Address Resolution Protocol (ARP) (0806) packets and responds with its own MAC address (proxy ARP). Everything else is dropped.
  • The Ethernet must contain only two IP devices: PE router and CE router. The PE router performs proxy ARP and responds to all ARP requests it receives. Therefore, only one CE router and one PE router should be on the Ethernet segment.
  • If the CE routers are doing static routing, you can perform the following tasks:
    • The PE router needs to learn the MAC address of the CE router to correctly forward traffic to it. The Ethernet PE router sends an Internet Control Message Protocol (ICMP) Router Discovery Protocol (RDP) solicitation message with the source IP address as zero. The Ethernet CE router responds to this solicitation message. To configure the Cisco CE router’s Ethernet interface to respond to the ICMP RDP solicitation message, issue the ip irdp command in interface configuration mode. If you do not configure the CE router, traffic is dropped until the CE router sends traffic toward the PE router.
    • To disable the CE routers from running the router discovery protocol, issue the ip irdp maxadvertinterval 0 command in interface configuration mode.
  • When you change the interworking configuration on an Ethernet PE router, clear the ARP entry on the adjacent CE router so that it can learn the new MAC address. Otherwise, you might experience traffic drops.

Restrictions for PPP Interworking

The following restrictions apply to PPP interworking:

  • There must be a one-to-one relationship between a PPP session and the pseudowire. Multiplexing of multiple PPP sessions over the pseudowire is not supported.
  • Only IP (IPv4 (0021) interworking is supported. Link Control Protocol (LCP) packets and Internet Protocol Control Protocol (IPCP) packets are terminated at the PE router. Everything else is dropped.
  • By default, the PE router assumes that the CE router knows the remote CE router’s IP address.
  • Password Authentication Protocol (PAP) and Challenge-Handshake Authentication Protocol (CHAP) authentication are supported.

Restrictions for Ethernet/VLAN-to-ATM AAL5 Interworking

The Ethernet/VLAN to ATM AAL5 Any Transport over MPLS (AToM) has the following restrictions:

  • Only the following translations are supported; other translations are dropped:
    • Ethernet without LAN FCS (AAAA030080C200070000)
    • Spanning tree (AAAA030080C2000E)
  • The ATM encapsulation type supported for bridged interworking is aal5snap. However, ATM encapsulation types supported for routed interworking are aal5snap and aal5mux.
  • The existing QoS functionality for ATM is supported, including setting the ATM CLP bit.
  • Only ATM AAL5 VC mode is supported. ATM VP and port mode are not supported.
  • SVCs are not supported.
  • Individual AAL5 ATM cells are assembled into frames before being sent across the pseudowire.
  • Non-AAL5 traffic, (such as Operation, Administration, and Maintenance (OAM) cells) is punted to be processed at the route processor (RP) level. A VC that has been configured with OAM cell emulation on the ATM PE router (using the oam-ac emulation-enable CLI command) can send end-to-end F5 loopback cells at configured intervals toward the CE router.
  • When the pseudowire is down, an F5 end-to-end segment alarm indication signal/remote defect indication (AIS/RDI) is sent from the PE router to the CE router.
  • If the Ethernet frame arriving from the Ethernet CE router includes a 802.1Q header (VLAN header), due to the type of endpoint attachment (Ethernet port mode), the VLAN header stays in the frame across the pseudowire (see the figure below).
Figure 1. Protocol Stack for ATM-to-Ethernet AToM Bridged Interworking--with VLAN Header

Restrictions for Ethernet/VLAN-to-Frame Relay Interworking

The Ethernet/VLAN-to-Frame Relay AToM has the following restrictions:

  • Only the following translations are supported; other translations are dropped:
    • Ethernet without LAN FCS (0300800080C20007)
    • Spanning tree (0300800080C2000E)
  • The PE router automatically supports translation of both Cisco and IETF Frame Relay encapsulation types coming from the CE router, but translates only to IETF when sending to the CE router. This is not a problem for the Cisco CE router, because it can manage IETF encapsulation upon receipt even if it is configured to send a Cisco encapsulation.
  • The PVC status signaling works the same way as in the like-to-like case. The PE router reports the PVC status to the CE router based upon the availability of the pseudowire.
  • The AC maximum transmission unit (MTU) must be within the supported range of MTUs when connected over MPLS.
  • Only Frame Relay DLCI mode is supported. Frame Relay port mode is not supported.
  • If the Ethernet frame includes a 802.1Q header (VLAN header), due to the type of endpoint attachment (Ethernet port mode), the VLAN header stays in the frame across the pseudowire (see the figure below).
  • Frame Relay encapsulation types supported for routed interworking are Cisco and IETF for incoming traffic. However, IETF is also supported for outgoing traffic traveling to the CE router.
Figure 2. Protocol Stack for Frame Relay-to-Ethernet AToM Bridged Interworking--with VLAN Header

Restrictions for HDLC-to-Ethernet Interworking

  • The “none CISCO” High-Level Data Link Control (HDLC) encapsulation is not supported.
  • IPv6 is not supported in routed mode.

Information About L2VPN Interworking

Overview of L2VPN Interworking

L2 transport over MPLS and IP already exists for like-to-like ACs, such as Ethernet-to-Ethernet or PPP-to-PPP. L2VPN Interworking builds on this functionality by allowing disparate ACs to be connected. An interworking function facilitates the translation between the different L2 encapsulations.

Only the following interworking combinations are supported:

  • ATM-to-Ethernet - Routed interworking
  • ATM-to-Ethernet - Bridged interworking
  • Frame relay-to-Ethernet - Bridged interworking
  • PPP-to-Ethernet - Routed interworking
  • HDLC-to-Ethernet - Bridged and Routed interworking

L2VPN Interworking Modes

L2VPN interworking works in either Ethernet (bridged) mode or IP (routed) mode. L2VPN interworking does not support Ethernet VLAN (Type 4) mode. You specify the mode in the following ways:

  • If using the older legacy CLI commands, you can use the interworking {ethernet | ip} command in pseudowire-class configuration mode.
  • If using the newer L2VPN protocol-based CLI commands, you can use the interworking {ethernet | ip} command in xconnect configuration mode.

The interworking command causes the ACs to be terminated locally. The two keywords perform the following functions:

  • The ethernet keyword causes Ethernet frames to be extracted from the AC and sent over the pseudowire. Ethernet end-to-end transmission is resumed. AC frames that are not Ethernet are dropped. In the case of VLAN, the VLAN tag is removed, leaving an untagged Ethernet frame.
  • The ip keyword causes IP packets to be extracted from the AC and sent over the pseudowire. AC frames that do not contain IPv4 packets are dropped.

The following sections explain more about Ethernet and IP interworking modes.

Ethernet or Bridged Interworking

Ethernet interworking is also called bridged interworking. Ethernet frames are bridged across the pseudowire. The CE routers could be natively bridging Ethernet or could be routing using a bridged encapsulation model, such as Bridge Virtual Interface (BVI) or Routed Bridge Encapsulation (RBE). The PE routers operate in Ethernet like-to-like mode.

This mode is used to offer the following services:

  • LAN services--An example is an enterprise that has several sites, where some sites have Ethernet connectivity to the service provider (SP) network and others have ATM connectivity. If the enterprise wants LAN connectivity to all its sites, traffic from the Ethernet or VLAN of one site can be sent through the IP/MPLS network and encapsulated as bridged traffic over an ATM VC of another site.
  • Connectivity services--An example is an enterprise that has different sites that are running an Internal Gateway Protocol (IGP) routing protocol, which has incompatible procedures on broadcast and nonbroadcast links. The enterprise has several sites that are running an IGP, such as Open Shortest Path First (OSPF) or Intermediate System-to-Intermediate System (IS-IS), between the sites. In this scenario, some of the procedures (such as route advertisement or designated router) depend on the underlying L2 protocol and are different for a point-to-point ATM connection versus a broadcast Ethernet connection. Therefore, the bridged encapsulation over ATM can be used to achieve homogenous Ethernet connectivity between the CE routers running the IGP.

IP or Routed Interworking

IP interworking is also called routed interworking. The CE routers encapsulate the IP on the link between the CE router and PE router. A new VC type is used to signal the IP pseudowire in MPLS. Translation between the L2 and IP encapsulations across the pseudowire is required. Special consideration needs to be given to the address resolution and routing protocol operation, because these are handled differently on different L2 encapsulations.

This mode is used to provide IP connectivity between sites, regardless of the L2 connectivity to these sites. It is different from a Layer 3 VPN because it is point-to-point in nature and the service provider does not maintain any customer routing information.

Address resolution is encapsulation dependent:

  • Ethernet uses Address Resolution Protocol (ARP)
  • ATM uses inverse ARP
  • PPP uses IP Control Protocol (IPCP)
  • HDLC uses Serial Line ARP (SLARP)

Therefore, address resolution must be terminated on the PE router. End-to-end address resolution is not supported. Routing protocols operate differently over broadcast and point-to-point media. For Ethernet, the CE routers must either use static routing or configure the routing protocols to treat the Ethernet side as a point-to-point network.

In routed interworking, IP packets that are extracted from the ACs are sent over the pseudowire. The pseudowire works in the IP Layer 2 transport (VC type 0x000B) like-to-like mode. The interworking function at network service provider’s (NSP) end performs the required adaptation based on the AC technology. Non-IPv4 packets are dropped.

In routed interworking, the following considerations are to be kept in mind:

  • Address resolution packets (ARP), inverse ARP, and IPCP are punted to the routing protocol. Therefore, NSP at the PE router must provide the following functionality for address resolution:
    • Ethernet--PE device acts as a proxy-ARP server to all ARP requests from the CE router. The PE router responds with the MAC address of its local interface.
    • ATM and Frame Relay point-to-point--By default, inverse ARP does not run in the point-to-point Frame Relay or ATM subinterfaces. The IP address and subnet mask define the connected prefix; therefore, configuration is not required in the CE devices.
  • Interworking requires that the MTUs in both ACs match for the pseudowire to come up. The default MTU in one AC should match with the MTU of other AC. The table below lists the range of MTUs that can be configured for different ACs.
Table 1 Range of MTUs for Different ACs

AC type

Range of MTUs supported

ATM

64 to 17940

Gigabit Ethernet

1500 to 4470

POS

64to 9102

Fast Ethernet

64to 9192


Note

The MTU configured on the AC should not exceed the MTU in the core network. This ensures that the traffic is not fragmented.

  • The CE routers with Ethernet attachment VCs running OSPF must be configured with the ospfIfTypeoption so that the OSPF protocol treats the underlying physical broadcast link as a P2P link.

Ethernet VLAN-to-ATM AAL5 Interworking

The following topics are covered in this section:

ATM AAL5-to-Ethernet Port AToM--Bridged Interworking

This interworking type provides interoperability between the ATM attachment VC and Ethernet attachment VC connected to different PE routers. Bridged encapsulation corresponding to the bridged (Ethernet) interworking mechanism is used.

The interworking function is performed at the PE router connected to the ATM attachment VC based on multiprotocol encapsulation over ATM AAL5 (see the figure below).

Figure 3. Network Topology for ATM-to-Ethernet AToM Bridged Interworking

The advantage of this architecture is that the Ethernet PE router (connected to the Ethernet segment) operates similarly to Ethernet like-to-like services.

On the PE router with interworking function, in the direction from the ATM segment to MPLS cloud, the bridged encapsulation (ATM/subnetwork access protocol (SNAP) header) is discarded and the Ethernet frame is encapsulated with the labels required to go through the pseudowire using the VC type 5 (Ethernet) (see the figure below).

In the opposite direction, after the label disposition from the MPLS cloud, Ethernet frames are encapsulated over AAL5 using bridged encapsulation.

The figure below shows the protocol stack for ATM-to-Ethernet AToM bridged interworking. The ATM side has an encapsulation type of aal5snap.

Figure 4. Protocol Stack for ATM-to-Ethernet AToM Bridged Interworking--without VLAN Header

ATM AAL5-to-Ethernet VLAN 802.1Q AToM--Bridged Interworking

This interworking type provides interoperability between the ATM attachment VC and Ethernet VLAN attachment VC connected to different PE routers. Bridged encapsulation corresponding to the bridged (Ethernet) interworking mechanism is used.

The interworking function is performed in the same way as for the ATM-to-Ethernet port case, implemented on the PE router connected to the ATM attachment VC. The implementation is based on multiprotocol encapsulation over ATM AAL5 (see the figure below).

For the PE router connected to the Ethernet side, one major difference exists due the existence of the VLAN header in the incoming packet. The PE router discards the VLAN header of the incoming frames from the VLAN CE router, and the PE router inserts a VLAN header into the Ethernet frames traveling from the MPLS cloud. The frames sent on the pseudowire (with VC type 5) are Ethernet frames without the VLAN header.

Encapsulation over ATM AAL5 is shown in the figure below.

Figure 5. Protocol Stack for ATM -to-VLAN AToM Bridged Interworking

ATM-to-Ethernet--Routed Interworking

To perform routed interworking, both the ATM PE router and Ethernet PE router must be configured. The figure below shows the routed interworking between ATM to Ethernet. The IP encapsulation over the pseudowire is performed on the ATM packets arriving from the ATM CE router.

The address resolution is done at the ATM PE router; it is required when the ATM CE router does an inverse ARP. It is not required when the ATM CE router is configured using Point-to-Point (P2P) subinterfaces or static maps.

When packets arrive from the Ethernet CE router, the Ethernet PE router removes the L2 frame tag, and then forwards the IP packet to the egress PE router, using IPoMPLS encapsulation over the pseudowire. The Ethernet PE router makes the forwarding decision based on the L2 circuit ID, the VLAN ID, or port ID, of the incoming L2 frame. At the ATM PE router, after label disposition, the IP packets are encapsulated over the AAL5 using routed encapsulation based on RFC 2684.

The address resolution at the Ethernet PE router can be done when the Ethernet CE router configures the static ARP, or by the proxy ARP on the Ethernet PE router. If the proxy ARP is used, the IP address of the remote CE router can be learned dynamically.

Routing protocols need to be configured to operate in the P2P mode on the Ethernet CE router.

Figure 6. Protocol Stack for ATM-to-Ethernet--Routed Interworking

Ethernet VLAN-to-Frame Relay Interworking

The following topics are covered in this section:

Frame Relay DLCI-to-Ethernet Port AToM--Bridged Interworking

This interworking type provides interoperability between the Frame Relay attachment VC and Ethernet attachment VC connected to different PE routers. Bridged encapsulation corresponding to the bridged (Ethernet) interworking mechanism is used.

For an FR-to-Ethernet port case, the interworking function is performed at the PE router connected to the FR attachment VC based on multiprotocol interconnect over Frame Relay (see the figure below). The interworking is implemented similar to an ATM-to-Ethernet case.

Figure 7. Network Topology for FR-to-Ethernet AToM Bridged Interworking

The advantage of this architecture is that the Ethernet PE router (connected to the Ethernet segment) operates similar to Ethernet like-to-like services: a pseudowire label is assigned to the Ethernet port and then the remote Label Distribution Protocol (LDP) session distributes the labels to its peer PE router. Ethernet frames are carried through the MPLS network using Ethernet over MPLS (EoMPLS).

On the PE router with interworking function, in the direction from the Frame Relay segment to the MPLS cloud, the bridged encapsulation (FR/SNAP header) is discarded and the Ethernet frame is encapsulated with the labels required to go through the pseudowire using the VC type 5 (Ethernet) (see the figure below).

In the opposite direction, after the label disposition from the MPLS cloud, Ethernet frames are encapsulated over Frame Relay using bridged encapsulation.

The following translations are supported:

  • Ethernet without LAN FCS (0300800080C20007)
  • Spanning tree (0300800080C2000E)

The PE router automatically supports translation of both Cisco and IETF Frame Relay encapsulation types coming from the CE, but translates only to IETF when sending to the CE router. This is not a problem for the Cisco CE router, because it can handle IETF encapsulation on receipt even if it is configured to send Cisco encapsulation.

The existing QoS functionality for Frame Relay is supported. The PVC status signaling works the same way as in the like-to-like case. The PE router reports the PVC status to the CE router, based on the availability of the pseudo wire.

The AC MTU must match when connected over MPLS. Only Frame Relay DLCI mode is supported; Frame Relay port mode is not supported in the bridged interworking.

The figure below shows the protocol stack for FR-to-Ethernet bridged interworking.

Figure 8. Protocol Stack for FR-to-Ethernet AToM Bridged Interworking--without VLAN Header

Frame Relay DLCI-to-Ethernet VLAN 802.1Q AToM--Bridged Interworking

This interworking type provides interoperability between the Frame Relay attachment VC and Ethernet VLAN Attachment VC connected to different PE routers. The bridged encapsulation corresponding to the bridged (Ethernet) interworking mechanism is used.

The interworking function is performed in the same way as it is done for the Frame Relay to Ethernet port case; it is implemented on the PE router connected to the Frame Relay attachment VC, based upon a multiprotocol interconnect over Frame Relay (see the figure above).

As in the ATM-to-VLAN case, one difference exists on the Ethernet side due the existence of the VLAN header in the incoming packet. The PE router on the VLAN side discards the VLAN header of the incoming frames from the VLAN CE router, and the PE router inserts a VLAN header into the Ethernet frames traveling from the MPLS cloud. The frames sent on the pseudowire (with VC type 5) are Ethernet frames without the VLAN header.

The figure below shows the protocol stack for FR-to-VLAN AToM bridged interworking.

Figure 9. Protocol Stack for FR-to-VLAN AToM Bridged Interworking

Frame Relay DLCI-to-Ethernet VLAN Qot1Q QinQ AToM - Bridged Interworking

This interworking type provides interoperability between the Frame Relay Attachment VC and Ethernet VLAN Attachment VC connected to different PE routers. The bridged encapsulation corresponding to bridged (Ethernet) interworking mechanism is used.

The interworking function is done in the same way as it is done for FR-to-Ethernet port case; it is implemented on the PE router connected to the Frame Relay attachment VC, based on RFC 2427(Multiprotocol Interconnect over Frame Relay).

When compared with Frame Relay DLCI-to-Ethernet port AToM, there is one major difference on the Ethernet access side, due the existence of the VLAN header in the incoming packet. The PE router on the VLAN side will discard the VLAN header of the incoming frames form the VLAN CE router, and it will insert a VLAN header into the Ethernet frames coming from the MPLS cloud. So the frames sent on the pseudo wire (with VC type 5) will be Ethernet frames without the VLAN header.

The following translations are supported on the Frame Relay PE router:

  • Ethernet without LAN FCS (0300800080C20007)
  • Spanning tree (0300800080C2000E)

Frame Relay encapsulation types supported for bridged interworking: Cisco and IETF for incoming traffic, IETF only for outgoing traffic towards CE router.

HDLC-to-Ethernet Interworking

High-Level Data Link Control (HDLC) and Ethernet are two independent data link layer transport protocols that utilize the Any Transport over MPLS (AToM) framework to communicate with each other. The interworking function enables translation between two heterogeneous Layer 2 encapsulations over a Multiprotocol Label Switching (MPLS) backbone.

The figure below depicts a simple HDLC-to-Ethernet interworking topology.

Figure 10. HDLC-to-Ethernet interworking topology

HDLC-to-Ethernet interworking supports the following:

  • Ethernet or bridged interworking
  • IP or routed interworking
  • HDLC encapsulation type: CISCO
  • Ethernet encapsulation types: IEEE 802.1Q, QinQ, port mode

The HDLC pass-through feature is not affected in any way by HDLC-to-Ethernet interworking.

HDLC-to-Ethernet interworking supports two interworking modes:

  • HDLC-to-Ethernet — Ethernet or Bridged interworking
  • HDLC-to-Ethernet — IP or Routed interworking

HDLC-to-Ethernet — Ethernet or Bridged Interworking

HDLC-to-Ethernet bridged interworking provides interoperability between the HDLC attachment virtual circuit (VC) and Ethernet VLAN attachment VC connected to different provider edge (PE) devices. Bridged encapsulation corresponding to the bridged (Ethernet) interworking mechanism is used.

When packets arrive from the HDLC customer edge (CE) device, they consist of the HDLC header, the Ethernet MAC header, and the payload. At the HDLC PE device, the HDLC header is removed, and MPLS labels are inserted. The frames are then routed over the pseudowire to the Ethernet PE device, where the MPLS labels are removed. On the Ethernet side, there are two possibilities. The attachment circuit (AC) is either Ethernet or VLAN.

For an Ethernet attachment circuit (AC), the packets are forwarded to the Ethernet CE device, as is. For a VLAN AC, VLAN headers are added at the VLAN/QinQ subinterface’s AC. The Ethernet VLAN frame is then forwarded to the VLAN CE device.

In the opposite direction (Ethernet / VLAN to HDLC), the VLAN header is present in the incoming packet, if the AC is VLAN. So, when packets arrive from the VLAN CE device, they consist of the VLAN header, the Ethernet MAC header, and the payload. At the Ethernet PE device, the VLAN header is removed at the VLAN/QinQ subinterface's AC, and MPLS labels are inserted. The frames are then routed over the pseudowire to the HDLC PE device, where the MPLS labels are removed. The HDLC header is added before the Ethernet MAC header. The HDLC frame is then forwarded to the HDLC CE device.

If the AC is Ethernet, packets arriving from the Ethernet CE device consist of the Ethernet MAC header and the payload. At the Ethernet PE device, MPLS labels are inserted at the VLAN/QinQ subinterface's AC. The frames are then routed over the pseudowire to the HDLC PE device, where the MPLS labels are removed. The HDLC header is added before the Ethernet MAC header. The HDLC frame is then forwarded to the HDLC CE device.

The figure below shows the bridged interworking mode of HDLC-to-Ethernet interworking, with a VLAN AC on the Ethernet side.

Figure 11. HDLC-to-Ethernet — Ethernet or Bridged Interworking

HDLC-to-Ethernet — IP or Routed Interworking

To perform routed interworking, both the HDLC PE device and Ethernet PE device must be configured. The IP encapsulation over the pseudowire is performed on HDLC packets that arrive from the HDLC CE device. The address resolution is done at the HDLC PE device.

When packets arrive from the HDLC CE device, they consist of the HDLC header, the IPv4 header, and the payload. At the HDLC PE device, the HDLC header is removed, and MPLS labels are inserted. The frames are then routed over the pseudowire to the Ethernet PE device, where the MPLS labels are removed. On the Ethernet side, there are two possibilities. The attachment circuit (AC) is either Ethernet or VLAN.

For an Ethernet attachment circuit (AC), the packets are forwarded to the Ethernet CE device, as is. For a VLAN AC, VLAN headers are added at the VLAN/QinQ subinterface’s AC. The Ethernet VLAN frame is then forwarded to the VLAN CE device.

In the opposite direction (Ethernet / VLAN to HDLC), the VLAN header is present in the incoming packet, if the AC is VLAN. So, when packets arrive from the VLAN CE device, they consist of the VLAN header, the Ethernet MAC header, and the payload. At the Ethernet PE device, the MAC header is removed, the VLAN header is removed at the VLAN/QinQ subinterface's AC, and MPLS labels are inserted. The frames are then routed over the pseudowire to the HDLC PE device, where the MPLS labels are removed. The HDLC header is added before the IPv4 header. The HDLC frame is then forwarded to the HDLC CE device.

If the AC is Ethernet, packets arriving from the Ethernet CE device consist of the Ethernet MAC header and the payload. At the Ethernet PE device, the MAC header is removed, and MPLS labels are inserted. The frames are then routed over the pseudowire to the HDLC PE device, where the MPLS labels are removed. The HDLC header is added before the IPv4 header. The HDLC frame is then forwarded to the HDLC CE device.

The figure below shows the routed interworking mode of HDLC-to-Ethernet interworking, with a VLAN AC on the Ethernet side.

Figure 12. HDLC-to-Ethernet — IP or Routed interworking

VC-to-VC Local Switching

VC-to-VC local switching transports cells between two ATM attachment VCs on the same or different port on the PE router. The cells coming to the PE router can be AAL0 or AAL5 encapsulated ATM packets. ATM VC-to-VC local switching can be configured either on point-to-point interface or on multipoint interface.

There are two operation modes for managing OAM cells over ATM local switching interfaces:

  • OAM transparent mode: In this mode, the PE router transports F5 OAM cells transparently across local switching interfaces.
  • OAM local emulation mode: In this mode, the PE router does not transport OAM cells across local switching interfaces. Instead, the interfaces locally terminate and process F5 OAM cells.

In ATM single cell relay AAL0, the ATM virtual path identifier/virtual channel identifier (VPI/VCI) values of the ingress and egress ATM interfaces of a router must match. If L2 local switching is desired between two ATM VPIs and VCIs, which are on two different interfaces and have values that do not match, ATM AAL5 should be selected. However, if ATM AAL5 uses OAM transparent mode, the VPI and VCI values must match.

ATM OAM can be configured on ATM VC mode local switching AC using the oam-ac emulation-enableand oam-pvc manage commands. When emulation is enabled on the AC, all OAM cells going through the AC are punted to RP for local processing. The ATM common component processes OAM cells and forwards the cells towards the local CE router. This helps to detect the failures on the PE router by monitoring the response at the CE router end. When the oam-pvc manage command is enabled on the AC, the PVC generates end-to-end OAM loopback cells that verify connectivity on the VC.

The following example shows a sample configuration on the ATM PE router:

configure terminal

	no ip address
 	no atm enable-ilmi-trap

VP-to-VP Local Switching

VP-to-VP local switching transports cells between two VPs on the same port or different ports on the PE router. The cells coming to the PE router can be AAL0 encapsulated ATM packets only. ATM VP-to-VP local switching can be configured only on multipoint interfaces.

There are two operation modes for managing OAM cells over ATM local switching interfaces:

  • OAM transparent mode: In this mode, the PE router transports F4 OAM cells transparently across local switching interfaces.
  • OAM local emulation mode: In this mode, the PE router do not transport OAM cells across local switching interfaces. Instead, the interfaces locally terminate and process F4 OAM cells.

In ATM single cell relay AAL0, the ATM VPI values of the ingress and egress ATM interfaces on a router must match. If L2 switching is desired between two ATM VPIs which are on two different interfaces and have values that do not match, ATM AAL5 should be selected. If ATM AAL5 uses OAM transparent mode, the VPI value must match. Currently, the ATM VP-to-VP local switching supports only AAL0 encapsulation.

The following example shows a sample configuration on the ATM PE router: 

configure terminal
interface atm 4/0.100 multipoint
	no ip address
	no atm enable-ilmi-trap
atm pvp 100 l2transport
interface atm 5/0.100 multipoint
	no ip address
	no atm enable-ilmi-trap
atm pvp 100 l2transport
connect atm_ls atm 4/0 100 atm 5/0 100

PPP-to-Ethernet AToM-Routed Interworking

In this interworking type, one of the ACs is Ethernet and the other is PPP. Each link is terminated locally on the corresponding PE routers and the extracted layer 3 (L3) packets are transported over a pseudowire.

The PE routers connected to Ethernet and PPP ACs terminate their respective L2 protocols. The PPP session is terminated for both the LCP and the Network Control Protocol (NCP) layers. On the ingress PE router, after extracting L3 packets, each PE router forwards the packets over the already established pseudowire using MPoMPLS encapsulation. On the egress PE router, after performing label disposition, the packets are encapsulated based on the corresponding link layer and are sent to the respective CE router. This interworking scenario requires the support of MPoMPLS encapsulation by the PE routers.

In PPP-to-Ethernet AToM routed interworking mode IPCP is supported. Proxy IPCP is automatically enabled on the PE router when IP interworking is configured on the pseudowire. By default, the PE router gets the IP address it needs to use from the CE router. The PE router accomplishes this by sending an IPCP confreq with the IP address 0.0.0.0. The local CE router has the remote CE router's IP address configured on it. The following example shows a sample configuration on the PPP CE router:

interface serial2/0
 ip address 168.65.32.13 255.255.255.0
 encapsulation ppp
peer default ip address 168.65.32.14  *

If the remote CE router's IP address cannot be configured on the local CE router, then the remote CE router's IP address can be configured on the PE router using the ppp ipcp address proxy ip address command on the xconnect PPP interface of PE router. The following example shows a sample configuration on the PPP PE router:

pseudowire-class mp
 encapsulation mpls
 protocol ldp
 interworking ip
!
int se2/0
 encap ppp
 xconnect 10.0.0.2 200 pw-class mp
 ppp ipcp address proxy 168.65.32.14

In this interworking type, one of the ACs is Ethernet and the other is PPP. Each link is terminated locally on the corresponding PE routers and the extracted layer 3 (L3) packets are transported over a pseudowire.

The PE routers connected to Ethernet and PPP ACs terminate their respective L2 protocols. The PPP session is terminated for both the LCP and the Network Control Protocol (NCP) layers. On the ingress PE router, after extracting L3 packets, each PE router forwards the packets over the already established pseudowire using MPoMPLS encapsulation.

This interworking scenario requires the support of MPoMPLS encapsulation by the PE routers.

In PPP-to-Ethernet AToM routed interworking mode IPCP is supported. Proxy IPCP is automatically enabled on the PE router when IP interworking is configured on the pseudowire. By default, the PE router gets the IP address it needs to use from the CE router. The PE router accomplishes this by sending an IPCP confreq with the IP address 0.0.0.0. The local CE router has the remote CE router's IP address configured on it. The following example shows a sample configuration on the PPP CE router:

interface serial2/0
 ip address 168.65.32.13 255.255.255.0
 encapsulation ppp
peer default ip address 168.65.32.14  *

If the remote CE router's IP address cannot be configured on the local CE router, then the remote CE router's IP address can be configured on the PE router using the ppp ipcp address proxy ip address command on the xconnect PPP interface of PE router. The following example shows a sample configuration on the PPP PE router:

template type pseudowire mp
 encapsulation mpls
 protocol ldp
 interworking ip
!
int se2/0
 encap ppp
interface pseudowire 100
 source template type pseudowire mp
 neighbor 33.33.33.33 1
!
l2vpn xconnect context con1 
 ppp ipcp address proxy 168.65.32.14

Static IP Addresses for L2VPN Interworking for PPP

If the PE router needs to perform address resolution with the local CE router for PPP, configure the remote CE router’s IP address on the PE router. Use the ppp ipcp address proxy command with the remote CE router’s IP address on the PE router’s xconnect PPP interface. The following example shows a sample configuration:

pseudowire-class ip-interworking
 encapsulation mpls
 interworking ip
interface Serial2/0
 encapsulation ppp
 xconnect 10.0.0.2 200 pw-class ip-interworking
 ppp ipcp address proxy 10.65.32.14

You can also configure the remote CE router’s IP address on the local CE router with the peer default ip address command if the local CE router performs address resolution.

Static IP Addresses for L2VPN Interworking for PPP using the commands associated with the L2VPN Protocol-Based CLIs feature

If the PE router needs to perform address resolution with the local CE router for PPP, configure the remote CE router’s IP address on the PE router. Use the ppp ipcp address proxy command with the remote CE router’s IP address on the PE router’s xconnect PPP interface. The following example shows a sample configuration:

template type pseudowire ip-interworking
 encapsulation mpls
 interworking ip
interface Serial2/0
 encapsulation ppp
interface pseudowire 100
 source template type pseudowire ip-interworking
 neighbor 10.0.0.2 200

                            What to Do Next


                            Note

                            When configuring bridged interworking, the PE2 router configuration does not include the interworking ethernetcommand because it is treated as like-to-like, and also because the AC is already an Ethernet port. However, when configuring routed interworking, the PE2 router configuration does include the interworking ip command.

                              Note

                              When configuring bridged interworking, the PE2 router configuration does not include the interworking ethernetcommand because it is treated as like-to-like, and also because the AC is already an Ethernet port. However, when configuring routed interworking, the PE2 router configuration does include the interworking ip command.
