Feature Description

Proxy Mobile IPv6 (PMIPv6) is a network-based mobility management protocol to provide mobility without requiring the participation of the mobile node in any PMIPv6 mobility-related signaling. The core functional entities, Mobile Access Gateway (MAG), and the Local Mobility Anchor (LMA), set up tunnels dynamically to manage mobility for a mobile node.

In an earlier release, support was added for the standardized PMIPv6 protocol between the NEMO and an SAEGW running on the ASR 5500. This support included processing of IPv4 prefixes at NEMO-LMA with IPv4 transport. With this release, the support is extended, including Session Recovery and ICSR support, for the following functionalities:

  • Processing (add/modify/delete) of IPv6 and IPv4v6 prefixes at NEMO-LMA with IPv4 transport.

  • Processing (add/modify/delete) of IPv4, IPv6, and IPv4v6 prefixes at NEMO-LMA with IPv6 transport.

  • Generation of UDR for base call containing NEMO IPv4, IPv6, or both IPv4 and IPv6 prefixes information for NEMO IPv4 transport only.

  • Heart beat support for NEMO-LMA with IPv6 transport.

UDR Support

UDR with NEMO prefixes information is generated for the base call in the following cases for NEMO IPv4 transport:

  • During initial NEMO call registration where UDR contains all the NEMO prefixes (IPv4, IPv6, or both IPv4 and IPv6), and number of prefixes.

  • During renew/update of NEMO prefixes where UDR contains only the new NEMO prefixes (IPv4, IPv6, or both IPv4 and IPv6 present in renew request), and number of prefixes.

  • During call cleanup:

    • If base call is cleared ahead of NEMO call, UDR with existing nemo prefixes is generated.

    • If NEMO call is cleared ahead of base call, UDR without prefixes is generated (as NEMO information is already deleted).

License Requirements

Use of NEMO requires that a valid license key be installed. Contact your Cisco account or Support representative for information on how to obtain a license.
