Configuring Proxy Mobile IPv6 Local Mobility Anchor

Local Mobility Anchor (LMA) acts as the home agent for a mobile node (MN) in a Proxy Mobile IPv6 domain, which is the network where the mobility management of an MN is handled using the Proxy Mobile IPv6 (PMIPv6) protocol. LMA is the topological anchor point for the MN’s home network prefix(es) and is the entity that manages the MN’s binding state. This module explains how to configure LMA on Cisco ASR 9000 Series Aggregation Services Routers.


Note

For a complete description of the PMIPv6 LMA configuration commands listed in this module, refer to the Cisco ASR 9000 Series Aggregation Services Router IP Addresses and Services Command Reference publication.

Information About Proxy Mobile IPv6 Support for LMA Functionality

Proxy Mobile IPv6 Overview

Proxy Mobile IPv6 (PMIPv6) provides network-based IP Mobility management to a mobile node (MN), without requiring the participation of the MN in any IP mobility-related signaling. The mobility entities in the network track the movements of the MN, initiate the mobility signaling, and set up the required routing state.

The major functional entities of PMIPv6 are Mobile Access Gateways (MAGs), Local Mobility Anchors (LMAs), and MNs.

Mobile Access Gateway

A Mobile Access Gateway (MAG) performs mobility-related signaling on behalf of the mobile nodes (MN) attached to its access links. MAG is the access router for the MN; that is, the MAG is the first-hop router in the localized mobility management infrastructure.

A MAG performs the following functions:

  • Obtains an IP address from a Local Mobility Anchor (LMA) and assigns it to an MN

  • Tunnels traffic from an MN to LMA

Local Mobility Anchor

Local Mobility Anchor (LMA) is the home agent for a mobile node (MN) in a Proxy Mobile IPv6 (PMIPv6) domain. It is the topological anchor point for MN home network prefixes and manages the binding state of an MN. An LMA has the functional capabilities of a home agent as defined in the Mobile IPv6 base specification (RFC 3775 and RFC 5213) along with the capabilities required for supporting the PMIPv6 protocol.

The LMA retains and shares the IP address of an MN when the MN roams across MAGs.

Smart Licensing for PMIPv6 LMA

Smart Licensing method of licensing is available for PMIPv6 LMA on the Cisco ASR 9000 Series Aggregation Services Routers. The licensing mode is soft-enforced mode. The licensing string available is A9K-SESSION-128K with maximum supported scale of 128K LMA bindings.

For more information about Smart Licensing, see Cisco ASR 9000 Series Aggregation Services Router System Management Configuration Guide.

Mobile Node

A mobile node (MN) is an IP host whose mobility is managed by the network. An MN can be an IPv4-only node, an IPv6-only node, or a dual-stack node, which is a node with IPv4 and IPv6 protocol stacks. An MN is not required to participate in any IP mobility-related signaling for achieving mobility for an IP address or a prefix that is obtained in the Proxy Mobile IPv6 (PMIPv6) domain.

VRF Aware LMA

This section contains the following topics:

VRF Aware LMA Solution

Local Mobility Anchor (LMA) supports VRF awareness on Cisco ASR 9000 Series Aggregation Services Routers. This feature includes the following capabilities:

  • Awareness of multiple customers belonging to different VRFs

  • Peer with multiple mobile operators for transport towards the Customer Premises Equipment (CPE)/Mobile Access Gateway (MAG) devices in separate peering or transport VRFs

  • AAA accounting for Mobile Nodes and tunnels

Topology

The following figure is a sample topology of Mobile Local Loop service hosted on Multiprotocol Label Switching (MPLS) multi-VRF Customer Edge (CE) routers:

The following figure is a sample topology of Mobile Local Loop service hosted on MPLS Provider Edge (PE) routers:

In these diagrams:

  • Mobile Local Loop (MLL) service allows enterprises Org A and Org B to securely link their remote small branch offices over mobile networks of Mobile Operator 1 and 2 without the need for dedicated leased lines or IP Security (IPSec) VPN cloud. The topologies are examples of MLL service deployment. The service uses Proxy Mobile IPv6 (PMIPv6) based overlay transport.

  • At the branch office, CPE/MAG devices such as Cisco ISR series routers are equipped with Cisco HWIC (High-Speed WAN Interface Card) 3G/4G service modules. These devices are used for IP connectivity and setting up overlay transport for service access.

  • MLL service provider hosts the LMA function of PMIPv6 and the MLL service on Cisco ASR 9000 series routers which could either be MPLS Provider Edge (PE) routers or MPLS Multi-VRF Customer Edge (CE) routers. LMA can peer with multiple mobile operators (such as Mobile Operators 1 and 2) to enable service access to CPE/MAG devices that can have connectivity to the mobile operators.

  • If accounting is enabled, LMA sends accounting records to AAA server with service usage counters.

Example:


RP/0/RSP0/CPU0:router(config-pmipv6-lma)# heartbeat interval 100 retries 5 timeout 10

Configures global LMA heartbeat options. interval-value specifies the interval between two heartbeat messages in seconds. retries-value specifies the number of retries (in the absence of reply from the peer) before the path to the peer is declared as down. timeout-value specifies the timeout value to wait for a response from the peer after which the request is declared as timed out.

Step 5

bce maximum number

Example:


RP/0/RSP0/CPU0:router(config-pmipv6-lma)# bce maximum 2500

Configures the maximum number of binding cache entries (BCEs) or bindings that the LMA can support.

Step 6

bce lifetime seconds

Example:


RP/0/RSP0/CPU0:router(config-pmipv6-lma)# bce lifetime 2500

Configures the permitted lifetime of a binding in seconds. The granted lifetime is minimum of this configured value and the value received from the MAG in the PBU packet.

Step 7

bce delete-wait-time milliseconds

Example:


RP/0/RSP0/CPU0:router(config-pmipv6-lma)# bce delete-wait-time 100

Configures the time in milliseconds that LMA must wait before it deletes a BCE of a MN, upon receiving a PBU message from a MAG with a lifetime value of 0.

Step 8

replay-protection timestamp window seconds

Example:


RP/0/RSP0/CPU0:router(config-pmipv6-lma)# replay-protection timestamp window 18

Configures the time window between the LMA’s running clock and the timestamp value received in the PBU from the MAG that the LMA can tolerate for the binding request to be accepted. If the calculated window is larger than this configured value, then the PBU is rejected with status code 156.

Step 9

bri delay { min | max } milliseconds

Configures the maximum number of times an LMA should retransmit a BRI message until a Binding Revocation Acknowledgment (BRA) is received from the MAG.

Step 11

dynamic mag learning

Example:


RP/0/RSP0/CPU0:router(config-pmipv6-lma)# dynamic mag learning

Enables an LMA to accept Proxy Mobile IPv6 (PMIPv6) signaling messages from any Mobile Access Gateway (MAG) that is not locally configured.

Step 12

aaa accounting [ interim interim-interval ]

Example:


RP/0/RSP0/CPU0:router(config-pmipv6-lma)# aaa accounting interim 2

Enables LMA accounting. If the interim interim-interval option is specified, Interim-Update records are sent to the RADIUS security server at the configured interim-interval specified in minutes. Otherwise, only Start and Stop records are sent to the RADIUS security server.

There are two types of accounting sessions, one for Mobile Nodes and one for tunnels. Interim-Update records are enabled only for tunnel accounting and not for Mobile Node accounting. For information about AAA/RADIUS configuration for accounting, see the Authentication, Authorization, and Accounting Commands chapter in Cisco ASR 9000 Series Aggregation Services Router System Security Command Reference.

Step 13

dscp control-plane dscp-value [ force ]

Example:


RP/0/RSP0/CPU0:router(config-pmipv6-lma)# dscp control-plane 45

Configures the value of Differentiated Services Code Point (DSCP) in the outgoing PMIPv6 control plane messages. The outgoing packets include locally generated packets such as Proxy Binding Revocation Indications (PBRIs), Proxy Binding Revocation Acknowledgments (PBRAs), Heartbeat Requests, and packets sent in response to packets received from MAG such as Proxy Binding Acknowledgments (PBAs), PBRIs, PBRAs, and Heartbeat Responses.

If dscp-value is not specified, then the DSCP received in a request is used in the outgoing response packet. DSCP is not set in the other outgoing packets.

If dscp-value is specified without the force option:

  • The configured DSCP value is set in locally generated packets.

  • If the received packet does not have DSCP marking, the configured value is set in the outgoing packet.

  • If the received packet has DSCP marking that matches the configured value, then the DSCP received is set in the outgoing response packet.

  • If the received packet has DSCP marking that does not match the configured value, then the DSCP received is used in the outgoing response packet.

If dscp-value is specified with the force option, then the configured DSCP value is set in all outgoing packets.

Example:


RP/0/RSP0/CPU0:router(config-pmipv6-lma)# mobility-service mobile-local-loop

Configures Mobile Loop Local (MLL) service on the LMA and enters the service configuration mode.

Step 15

customer customer-name vrf vrf-name

Example:


RP/0/RSP0/CPU0:router(config-pmipv6-lma-mll)# customer CUST1 vrf VRF1

Configures the name and the VRF of a customer. The command enters the customer configuration mode where other parameters of the customer are configured. Use the no form of this command to remove an existing customer. There can be many customers, however no two customers can be configured with the same VRF.

Step 16

auth-option spi hex-value key ascii value

Example:


RP/0/RSP0/CPU0:router(config-pmipv6-lma-mll-cust)# auth-option spi 87E key ascii KEY1

Configures customer-specific authentication for the LMA within the MLL. The authentication option includes an SPI value specified in hexadecimal format and a shared secret key which is specified as an ASCII string. This configuration overrides the global auth-option configuration in the PMIPv6 LMA Domain.

Step 17

heartbeat interval interval-value retries retries-value timeout timeout-value

Example:


RP/0/RSP0/CPU0:router(config-pmipv6-lma-mll-cust)# heartbeat interval 30 retries 10 timeout 10

Configures customer-specific heartbeat options. interval-value specifies the interval between two heartbeat messages in seconds. retries-value specifies the number of retries (in the absence of reply from the peer) before the path to the peer is declared as down. timeout-value specifies the timeout value to wait for a response from the peer after which the request is declared as timed out. This configuration overrides the global LMA heartbeat configuration.

Step 18

bce lifetime seconds

Example:


RP/0/RSP0/CPU0:router(config-pmipv6-lma-mll-cust)# bce lifetime 1500

Configures customer-specific permitted lifetime of binding cache entries (BCEs) in seconds. This configuration overrides the global LMA BCE configuration.

Step 19

network { unauthorized | authorized network-name }

Example:


RP/0/RSP0/CPU0:router(config-pmipv6-lma-mll-cust)# network authorized NETW1

Configures customer-specific network.

Use the unauthorized keyword to configure an unauthorized network. In this case, no network pools are configured for address assignment. The address/prefix of the Logical Mobile Node (LMN) on the MAG and the network prefixes on the Mobile Network interfaces are accepted as received in the Proxy Binding Update (PBU).

Use the authorized keyword to configure a named network. In this case, the address/prefix of the LMN and Mobile Network prefixes are validated against the configured network pool. The uniqueness of the named network is ensured.

Use the no form of this command to remove an existing network.

Step 20

pool { mobile-node | mobile-network } { ipv4 | ipv6 } start-address address pool-prefix prefix [ network-prefix prefix]

Example:


RP/0/RSP0/CPU0:router(config-pmipv6-lma-mll-cust-network)# pool mobile-node ipv4 start-address 192.168.0.2 pool-prefix 8

Perform this step only if you have configured a named network in the previous step using the network authorized command. Configures the IPv4 or IPv6 address pool(s) from which LMA assigns IP addresses to the mobile nodes. The pool is characterized by whether it is for Mobile Nodes or Mobile Networks for the customer, whether it is for IPv4 or IPv6 address family, the start address of the pool, the pool prefix and the network prefix of the pool.

Step 21

transport [ vrf vrf-name ]

Example:


RP/0/RSP0/CPU0:router(config-pmipv6-lma-mll-cust)# transport vrf TVRF1

Configures customer’s transport options. They include peering or transport VRF and the LMA IPv4 and/or IPv6 addresses. The addresses are configured in the transport configuration mode using the address command.

A customer can have multiple transports and can have the same addresses in all transports. However, each customer must have a unique IPv4 and/or a unique IPv6 address.

Note 

If the transport is in global VRF, then VRF and vrf-name can be omitted in this command.

Step 22

address { ipv4 | ipv6 } address

Example:


RP/0/RSP0/CPU0:router(config-pmipv6-lma-mll-cust-tpt)# address ipv6 2001:DB8::1

Configures customer-specific LMA IPv4 and/or IPv6 addresses. There can only be two instances of addresses, one for IPv4 and one for IPv6.
