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.

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 Gateways

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, MAG is the first-hop router in the localized mobility management infrastructure.

MAG performs the following functions:

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

  • Retains the IP address of an MN when the MN roams across MAGs.

  • Tunnels traffic from 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) along with the capabilities required for supporting the PMIPv6 protocol.


Note

Use the dynamic mag learning command to enable LMA to accept Proxy Mobile IPv6 (PMIPv6) signaling messages from any Mobile Access Gateway (MAG) that is not configured locally.

Mobile Node

Mobile node (MN) is an IP host and the mobility of the MN is managed by a network. 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. 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

The VRF Aware LMA feature is an enhancement that enables VRF awareness support on Local Mobility Anchor (LMA). 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) or Mobile Access Gateway (MAG) devices in separate peering or transport VRFs.

AAA Server Attributes for Proxy Mobile IPv6

If an authentication, authorization, and accounting (AAA) server is available, a Mobile Access Gateway (MAG) obtains the profile information of the Proxy Mobile IPv6 (PMIPv6) domain and the mobile node (MN) from the server during the configuration and call-flow time, respectively.

The following are the AAA attributes required for configuring the PMIPv6 domain and the MN are:

  • PMIPv6 domain-specific AAA attributes:
    • cisco-mpc-protocol-interface
    • lma-identifier
    • mag-identifier
    • mag-v4-address
    • mag-v6-address
    • pmip6-domain-identifier
    • pmip6-timestamp-window
    • pmip6-replay-protection
    • pmip6-spi-key
    • pmip6-spi-value
  • MN-specific AAA attributes:
    • home-lma
    • home-lma-ipv6-address
    • mn-nai
    • home-lma-ipv4-address
    • mn-apn
    • Mobile-Node-Identifier
    • mn-network
    • mn-service
    • multihomed

Proxy Mobile IPv6 Local Mobility Anchor

15.5(2)T

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.
