The Proxy Mobile IPv6 protocol supports Mobile Hosts moving
independently, but not Mobile Routers in charge of moving networks.
This draft addresses this problem. The goal is to allow
bidirectional communication between a Local Fixed Node (in the moving
network) and a Correspondent Node (situated arbitrarily somewhere in
the Internet). First, a mechanism of "prefix division" is presented,
whereby the Home Network Prefix typically assigned by PMIPv6 to a MH
is used by MR to form Mobile Network sub-Prefix(es); they are used by
LFNs within the moving network to form addresses; this avoids changes
in the PMIPv6 protocol specification. A second mechanism proposes
enhancements to the use of the DHCPv6 Prefix Delegation protocol
entities informing the PMIPv6 entities about the allocated MNP; this
is achieved by equaling MNID and DUID.
