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 opWons 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. July 2016 TRILL WG 8

ARP/ND Op:miza:on Dra> • (conWnued) – MulWple cases of quesWonable RFC 2119 key words (MUST / SHOULD / MAY) need to be reviewed/fixed. July 2016 TRILL WG 9

Plan Going Forward • Respond to the 1 IESG DISCUSS (out of 3 DISCUSSes) not yet responded to. • Produce and post updated draN incorporaWng changes agreed to by Area Directors who had posted a discuss. (Agreement already reach for 2 out of 3.) • Run WG Last Call. – Resolve any comments. • Request PublicaWon July 2016 TRILL WG 10
