Feature Description

MAP-E support on 5th Generation ASR 9000 Series Line Cards

Release 7.4.1

MAP-E has been supported on Cisco ASR 9000 Series and Cisco ASR 9900 series 4th generation Ethernet line cards.

In this release, Map-E support is extended to the following Cisco ASR9000 Series and Cisco ASR 9900 Series 5th generation hardware:

  • A9K-20HG-FLEX-SE/TR

  • A9K-8HG-FLEX-SE/TR

  • A99-32X100GE-X-SE/TR

  • A99-10X400GE-X-SE/TR

  • A9K-4HG-FLEX-SE/TR

  • ASR-9903 fixed-port router and Port Expansion Cards (PECs)

  • ASR-9902 fixed-port router

This feature configures Mapping of Address and Portal-Encapsulation Mode (MAP-E) CGN solution without service cards (ISM or VSM). The CGN application directly interacts with the line cards to configure MAP-E.


Note
The MAP-E CGN solution without service cards (VSM/ISM) is supported on Cisco IOS XR and Cisco IOS XR 64 bit operating system.

Restrictions for Configuring MAP-E without Service Card on Cisco IOS XR 32-bit Operating System

  • MAP-E is supported on the 3rd and 4th generation of Cisco ASR 9000 Series Ethernet line cards.

  • MAP-E without service cards can be enabled only in a default VRF.

  • If MAP-E or MAP-T is enabled on an interface, other policy based routing (PBR) features such as CLI PBR, BGP Flow Spec, One Platform Kit (onePK), OpenFlow, ingress ACLs and BNG are not supported. This is because only one PBR policy is allowed on the interface per direction.

  • In a router, only one mode of either inline-service with service card or inline-service without service card is supported.

Restrictions for Configuring MAP-E without Service Card on Cisco IOS XR 64-bit Operating System

  • From Cisco IOS XR Release 7.0.1 onwards, Cisco ASR 9000 Series 4th Generation Ethernet line cards support MAP-E.

  • From Cisco IOS XR Release 7.4.1 onwards, Cisco ASR 9000 Series 5th Generation Ethernet line cards support MAP-E.

Types of exception packets handled only by Service Module:

  • IPv6 extension headers.

  • V4/V6 fragmented packets.

  • ICMP messages (excluding ICMP echo message and reply packets, which are processed by the inline interface for MAP-E)

  • TCP Maximum Segment Size and Path MTU checks.

  • Packets with Loose Source Route (LSR) and Strict Source Route (SSR) IPv4 options

MAP-T without Service Cards

The objective of this feature is to ensure that the Mapping of Address and Port-Translation Mode (MAP-T) CGN solution can be implemented without service cards (VSM/ISM). With this feature, the CGN application directly interacts with the line cards to configure the MAP-T parameters and eliminates the dependency on the service cards.


Note

The MAP-T CGN solution without service cards (VSM/ISM) is supported on Cisco IOS XR and Cisco IOS XR 64 bit operating system.

Restrictions for Configuring MAP-T without Service Card on Cisco IOS XR 32-bit Operating System

  • MAP-T is supported on Cisco ASR 9000 Series and Cisco ASR 9900 Series 3rd, 4th, and 5th generation Ethernet line cards.

  • If this feature is enabled on an interface, other PBR (policy based routing) features such as CLI PBR, BGP Flow Spec, One Platform Kit (onePK) or OpenFlow may not be functional; this is because only one PBR policy will be allowed on the interface.

  • In a router, only one mode of either inline-service with service card or inline-service without service card will be supported.

  • At a router level, the max scale limit for CPE domain parameters is 25 and for external domain parameters is 8k. If a single MAP-T instance has utilized 25 of CPE domain and 8k of external domain parameters; it is not possible to configure additional CPE and external domain parameters in the same router.

Restrictions for Configuring MAP-T without Service Card on Cisco IOS XR 64-bit Operating System

  • From Cisco IOS XR Release 7.0.1 onwards, Cisco ASR 9000 Series 4th Generation Ethernet line cards support MAP-T.

  • From Cisco IOS XR Release 7.1.2 onwards, Cisco ASR 9000 Series 5th Generation Ethernet line cards support MAP-T.

  • MAP-T can be enabled in normal unicast routing scenario with default VRF. With non-default VRF, MAP-T works only in L3VPN and 6VPE cloud.

  • For the IPv6 prefix length greater than 48 and less than 64 the sharing-ratio and contiguous-ports configurations are not considered during the translation.

  • The Exception and Fragmented packets are not supported with inline MAP-T.

  • In a single MAP-T instance only 255 CPE-domains are supported.


Note

When you configure the MAP-T on Cisco ASR 9000 fourth generation line cards, verify the value in the num free field of the TCAM table.

To verify the num free field values, use the show controller controllers rm tcam summary 640-ING all np all location <node-id> command.

The number of MAP-T external domains that you can configure is based on the num free field values. When you configure a number of MAP-T external domains that exceed the num free field value, it results in a complete loss of traffic.

Overview of MAP-T Logging

MAP-T Logging feature records and exports the IPv4 to IPv6 and IPv6 to IPv4 address translation information to the server. It captures all the following information and stores in the server as a template. It helps to map which IPv4 address translated to which corresponding IPv6 address, and vice versa.

A single translated flow captures the following details:

  • IPv4 source address

  • IPv4 destination address

  • Source port

  • Destination port

  • VRF name configured in CPE-domain

  • VRF name configured in EXT-domain

  • Timestamp

  • IPv6 source address

  • IPv6 destination address

Following is the detail information:

  • Ports are not being translated during MAP-T conversion so there is no pre-NAT or post-NAT display. Only one pair of IPv4 or IPv6 address or port is displayed in a MAP-T logging record.

  • There is no indication that MAP-T converted flow is IPv4 to IPv6 or IPv6 to IPv4.

  • The following information is displayed from the point of view IPv4 packet, which is IPv4 to IPv6:

    • The ingress VRF is of IPv4 address, and the egress VRF is of IPv6 address.

    • The Layer 4 destination port and source port are the same as seen in IPv4 packet header.

  • Flows with same address pair in different VRFs are considered as separate flows.

  • Any new flow that comes in, after 512k flows are learnt, is dropped. There is no MAP-T conversion for any new flow.

  • Output interface is not displayed in the records.

  • A 60 second timer runs by default for all flows. If any flow is active for 60 seconds, it is exported out. This is to ensure high availability. If a line card went down or there was a network process failure, all learned flow available in the system for at least 60 seconds will not be lost.

Restrictions

  • Ipv4 to IPv6 and IPv6 to IPv4 address translation flow for same pair of address is considered as a single flow if IPv4 to IPv6 and IPvV6 to IPv4 traffic is on same network process. Flow learning across different network process cannot be considered as the same flow on that line card. If they are on a different network process, they are considered as two different flow. Flow collector application can identify unique flows.

  • There is a 3-second deviation in flow expiration timer as it takes 3 seconds to scan all the 512k flows.
