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 and
reduce/suppress the flooding produced by the Address Resolution
procedure. However, if the Neighbor information is learnt via EVPN,
the PE would not know if a particular IPv6->MAC pair belongs to a
host, a router or a host with an anycast address as this information
is not carried in the MAC/IP route advertisements. This document
proposes an OPTIONAL advertisement of the Flags defined in [RFC4861]
along with the EVPN MAC/IP Advertisement routes, so that an EVPN PE
implementing a proxy-ND function can reply to Neighbor Solicitations
with the correct Flag information in Neighbor Advertisements.
