Proxy Mobile IPv6 Support for MAG Functionality

The Proxy Mobile IPv6 Support for MAG Functionality feature provides network-based IP Mobility management to a mobile node (MN) without requiring the participation of the mobile node in any IP Mobility-related signaling. The Mobile Access Gateway (MAG) tracks the movements of the MN to and from an access link and sends signals to the local mobility anchor of the MN.

Information About Proxy Mobile IPv6 Support for MAG 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 Awareness on PMIPv6 MAG

Each Logical Mobile Node (LMN) represents a customer and it is associated with an unique Local Mobility Anchor (LMA). As the LMNs belong to different virtual routing and forwarding (VRF) instances , the Mobility Access Gateway (MAG) requires being aware of the customer VRF. The MAG has no notion of the transport VRF. The VRF Awareness on PMIPv6 MAG feature enables the MAG to host multiple customers and provide Proxy Mobile IPv6 (PMIPv6) services to them.

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 MAG Functionality Support

              15.2(4)M

              The Proxy Mobile IPv6 Support for MAG Functionality feature provides network-based IP Mobility management to a MN without requiring the participation of the MN in any IP mobility-related signaling. The Mobile Access Gateway tracks the movements of the MN to and from the access link, and sends signals to the local mobility anchor of the MN.

              The following commands were introduced or modified: address (proxy mobile IPv6), apn (proxy mobile IPv6), auth-option, binding, bri, clear ipv6 mobile pmipv6 mag, debug ipv6 mobile mag, debug ipv6 mobile packets, discover-mn-detach, encap, fixed-link-layer-address, fixed-link-local-address, gre-encap-key, int att, interface, ipv4-address, ipv6 mobile pmipv6-domain, ipv6 mobile pmipv6-mag, ipv6-address, lma, local-routing-mag, mn-profile-load-aaa, multi-homed, nai (proxy mobile IPv6), replay-protection, role, service, show ipv6 mobile pmipv6 mag binding, show ipv6 mobile pmipv6 mag globals, and show ipv6 mobile pmipv6 mag stats.

              VRF Awareness in PMIPv6 MAG

              The VRF Awareness on PMIPv6 MAG feature enables the MAG to host multiple customers and provide PMIPv6 services to them.

              The following commands were introduced or modified:

              mobility-service mobile-local-loop, ignore homeaddress, and egress interface.
