Abstract:
The MAC/IP Advertisement route specified in [RFC7432] can optionally
carry IPv4 and IPv6 addresses associated with a MAC address. Remote
PEs 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 broadcast domains, where the amount of
ARP/ND flooded traffic causes issues on routers and CEs, as explained
in [RFC6820]. This document describes how the [RFC7432] EVPN proxy-
ARP/ND function may be implemented to help IXPs and other operators
deal with the issues derived from Address Resolution in large
broadcast domains.
