RFC 4651 MIP6 Route Optimization Enhancements February 2007
1. Introduction
Mobility support for IPv6, or Mobile IPv6, enables mobile nodes to
migrate active transport connections and application sessions from
one IPv6 address to another. The Mobile IPv6 specification, RFC 3775
[1], introduces a "home agent", which proxies a mobile node at a
permanent "home address". A roaming mobile node connects to the home
agent through a bidirectional tunnel and can so communicate, from its
local "care-of address", as if it was present at the home address.
The mobile node keeps the home agent updated on its current care-of
address via IPsec-protected signaling messages [40].
In case the correspondent node lacks appropriate mobility support, it
