Reserved IPv6 Interface Identifier for Proxy Mobile IPv6
Abstract
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.

1. Introduction
Proxy Mobile IPv6 [RFC5213] is a network-based mobility management
protocol that enables IP mobility support for a mobile node without
requiring its participation in any mobility-related signaling. The
mobility elements in the network ensure that the 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 and changes its
point of attachment in the network. All mobile access gateways in a
Proxy Mobile IPv6 domain use a fixed link-local address and a fixed
link-layer address on any of their access links that they share with
the mobile nodes. This essentially ensures that a mobile node, after
performing a handoff, does not detect any change with respect to the
IP network configuration.

RFC 6543 Reserved IPv6 IID for PMIPv6 May 2012
Although the base Proxy Mobile IPv6 specification [RFC5213] requires
the use of a fixed link-local and a fixed link-layer address, it did
not reserve any specific addresses for this purpose. This is proving
to be an operational challenge in deployments involving multi-vendor
equipment. To address this problem, this specification makes the
following two reservations.
1. This specification reserves one Ethernet unicast address,
00-00-5E-00-52-13, for use with Proxy Mobile IPv6. This reserved
link-layer address SHOULD be used by the mobile access gateway in
a Proxy Mobile IPv6 domain, on all of the access links that it
