Proxy Mobile IPv6 (RFC 5213) requires that all mobile access gateways
use a fixed link-local address and a fixed link-layer address on any
of their access links that they share with mobile nodes.  This
requirement was intended to ensure that a mobile node does not detect
any change with respect to its Layer 3 attachment, even after it
roams from one mobile access gateway to another.  In the absence of
any reserved addresses for this use, coordination across vendors and
manual configuration of these addresses on all of the mobility
elements in a Proxy Mobile IPv6 domain are required.  This document
attempts to simplify this operational requirement by making a
reservation for special addresses that can be used for this purpose.
This document also updates RFC 5213.  [STANDARDS-TRACK]
