Abstract:
The EVPN MAC/IP Advertisement route can optionally carry IPv4 and
IPv6 addresses associated with a MAC address. Remote PEs importing
those routes in the same Broadcast Domain (BD) can use this
information to reply locally (act as proxy) to IPv4 ARP requests and
IPv6 Neighbor Solicitation messages (or 'unicast-forward' them to the
owner of the MAC) and reduce/suppress the flooding produced by the
Address Resolution procedure. This EVPN capability is extremely
useful in Internet Exchange Points (IXPs) and Data Centers (DCs) with
large BDs, where the amount of ARP/ND flooded traffic causes issues
on connected routers and CEs. This document describes the EVPN
Proxy-ARP/ND function augmented by the capability of the ARP/ND
Extended Community, which together help IXPs and other operators to
deal with the issues derived from Address Resolution in large BDs.
