This document specifies extensions to the Ethernet VPN Integrated
Routing and Bridging (EVPN-IRB) procedures specified in RFCs 7432 and
9135 to enhance the mobility mechanisms for networks based on
EVPN-IRB. The proposed extensions improve the handling of host
mobility and duplicate address detection in EVPN-IRB networks to
cover a broader set of scenarios where a host's unicast IP address to
Media Access Control (MAC) address bindings may change across moves.
These enhancements address limitations in the existing EVPN-IRB
mobility procedures by providing more efficient and scalable
solutions. The extensions are backward compatible with existing
EVPN-IRB implementations and aim to optimize network performance in
scenarios involving frequent IP address mobility.
This document is a product of the BGP Enabled ServiceS Working Group of the
IETF.
This is now a Proposed Standard.
