Prefix Delegation Support for Proxy Mobile IPv6
draft-ietf-netext-pd-pmip-12
Abstract
This specification defines extensions to the Proxy Mobile IPv6
protocol for allowing a mobile router in a Proxy Mobile IPv6 domain
to obtain IP prefixes for its attached mobile networks using DHCPv6
prefix delegation. Network-based mobility management support is
provided for those delegated IP prefixes just as it is provided for
the mobile node's home address. Even if the mobile router performs a
handoff and changes its network point of attachment, mobility support
is ensured for all the delegated IP prefixes and for all the IP nodes
in the mobile network that use IP address configuration from those
delegated IP prefixes.
