Proxy Mobile IPv6 Support for MAG Functionality

First Published: July 22, 2011
Last Updated: July 22, 2011

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

Proxy Mobile IPv6 Overview

Proxy Mobile IPv6 (PMIP) provides network-based IP Mobility management to an 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 the Mobile Access Gateways (MAG), the Local Mobility Anchors (LMA), and the MNs.

Mobile Access Gateways

The MAG is the entity that performs mobility-related signaling on behalf of the MNs attached to its access links. The MAG is the access router for the MN; that is, the first-hop router in the Localized Mobility Management infrastructure.

The major functions of the MAG are as follows:

•Obtain the IP address from the LMA and assign the address to the MN.

•Retain the IP address of the MN when the MN roams across the MAGs.

•Tunnel the traffic for the MN to the LMA.

Local Mobility Anchors

The LMA is the home agent for the MN in a PMIPv6 domain. It is the topological anchor point for the MN home network prefixes and is the entity that manages the MN's binding state. The LMA has the functional capabilities of a home agent as defined in Mobile IPv6 base specification (RFC 3775) along with the capabilities required for supporting PMIPv6 protocol.

Mobile Nodes

A mobile node is an IP host whose mobility is managed by the network. An MN can be an IPv4-only node, IPv6-only node, or a dual-stack node. The MN is not required to participate in any IP mobility-related signaling for achieving mobility for an IP address or for a prefix that is obtained in the PMIP domain.

AAA Server Attributes for Proxy Mobile IPv6

If the authentication, authorization, and accounting (AAA) server is available, the Mobile Access Gateway (MAG) obtains profile information for the PMIP domain and the MN from the server during configuration and call-flow time, respectively. The list of AAA attributes required for the PMIP domain and the MN follows:

•PMIP domain-specific AAA attributes:

–pmip6-timestamp-window

–lma-identifier

–mag-identifier

–pmip6-replay-protection

–pmip6-fixed-ll-address

–pmip6-fixed-l2-address

–pmip6-domain-identifier

•Mobile node-specific AAA attributes:

–home-lma

–mn-nai

–multihomed

–home-lma-ipv6-address

–mn-service

Troubleshooting Tips

The following commands can help troubleshoot MAG configuration:

•debug ipv6 mobile mag event

•debug ipv6 mobile mag info

•show ipv6 pmipv6 mag bindings

•show ipv6 pmipv6 mag globals

Configuration Examples for Proxy Mobile IPv6 Support for MAG Functionality

•Example: Configuring a Proxy Mobile IPv6 Domain Using the Configuration from a AAA Server

•Example: Configuring a Proxy Mobile IPv6 Domain When the Configuration from a AAA Server Is Not Available

•Example: Configuring a Mobile Access Group

Example: Configuring a Proxy Mobile IPv6 Domain Using the Configuration from a AAA Server

The following example shows how to configure the PMIP domain using a AAA configuration: 

Router# configure terminal

Router(config)# ipv6 mobile pmipv6-domain D1 load-aaa

The following example shows how to configure the PMIP domain using the configuration from a AAA server, and to override configuration for specific PMIP domain parameters: 

Router# configure terminal

Router(config)# ipv6 mobile pmipv6-domain D11 load-aaa

Router(config)# ipv6 mobile pmipv6-domain D11

Router(config-ipv6-pmipv6-domain)# gre-ipv4

Router(config-ipv6-pmipv6-domain)# auth-option spi 67 key ascii key1

Router(config-ipv6-pmipv6-domain-mn)# service ipv4

Router(config-ipv6-pmipv6-domain)# end

Example: Configuring a Mobile Access Group

The following example shows the minimum configuration required for the MAG to be functional: 

Router# configure terminal

Router(config)# ipv6 mobile pmipv6-domain D2

Router(config-ipv6-pmipv6-domain)# fixed-link-layer-address aaaa.bbbb.cccc

!

Router(config-ipv6-pmipv6-domain)# lma lma1

Router(config-ipv6-pmipv6-domain-lma)# ipv4-address 10.1.1.1

Router(config-ipv6-pmipv6-domain-lma)# ipv6-address 2001:0DB8:2:3::1

Router(config-ipv6-pmipv6-domain-lma)# exit

!

Router(config-ipv6-pmipv6-domain)# lma lma2

Router(config-ipv6-pmipv6-domain-lma)# ipv4-address 10.2.1.1

Router(config-ipv6-pmipv6-domain-lma)# ipv6-address 2001:0DB8:2:4::1

Router(config-ipv6-pmipv6-domain-lma)# exit

!

Router(config-ipv6-pmipv6-domain)# nai abc1@example.com

Router(config-ipv6-pmipv6-domain-mn)# lma lma1

Router(config-ipv6-pmipv6-domain-mn)# exit

!

Router(config-ipv6-pmipv6-domain)# nai abc2@example.com

Router(config-ipv6-pmipv6-domain-mn)# lma lma2

Router(config-ipv6-pmipv6-domain-mn)# exit

!

Router(config)# ipv6 mobile pmipv6-mag mag1 domain D2

Router(ipv6-mag-config)# address ipv6 5020::1

Router(ipv6-mag-config)# address ipv4 10.2.1.1 

Router(ipv6-mag-config)# interface gigabitethernet0/0/0

Router(ipv6-mag-config)# role 3gpp

Router(ipv6-mag-config)# apn a

Router(ipv6-mag-config)# exit

Where to Go Next

The MAG entity functions along with the LMA provided by ASR 5000. To configure the LMA in the Cisco ASR 5000, see the "PDN Gateway Configuration" chapter in the Cisco ASR 5000 Series Packet Data Network Gateway Administration Guide.

Proxy Mobile IPv6 MAG Functionality Support

Cisco IOS XE Release 3.4S

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

In Cisco IOS XE Release 3.4S, this feature was introduced on the Cisco ASR 1000 series routers.

The following sections provide information about this feature:

•Information About Proxy Mobile IPv6 Support for MAG Functionality

•Configuring a PMIPv6 Domain Using the Configuration from AAA Server

•Configuring a Minimum Configuration for the MAG to Function

•Configuring a Detailed Configuration When a AAA Server Is Not Available
