ARP/ND Op:miza:on Dra>

• DraN returned to the WG from the IESG. 3 DISCUSSes with the

following points:

– ANer an edge RBridge learns that an IP address is connected to it, what does it do about tesWng that it is sWll there?

• Various possibiliWes: Time-outs reset on seeing locally originated IP traffic;

periodic ARP/ND pings to the local staWon; …

– Needs guidance as to when to pick which of the a1 through a5

• pWons in SecWon 3.2.

– Needs guidance as to the source address of responses synthesized by edge Rbridge. – Needs to more clearly specify what to do in the case of SEND (Secure ND). That case rules out some opWons.
