And I suspect you mean Section 15.1 draft*evpn-inter-subnet-forwarding should call out this cross-reference explicitly, so that the reader does not have to speculate (as I just did) sajassi> AS> If ARP probing is done before the target NVE gets to declare that the TS has moved, then the MAC move is delayed unnecessarily for ALL the legitimate MAC move cases which in turn can cause some loss of traffic and degradation in service. It should be noted that the MAC move procedures in here is consistent with RFC 7432. sajassi> AS> same reply as above. it's a bit odd that lot of chaos can happen for approx 3 mins when there is actually a duplicate address (created accidentally or maliciously) but I suppose you could say that this is already based on 7431, so not something introduced by draft*evpn-inter-subnet-forwarding Thanks --Sowmini _______________________________________________ BESS mailing list [email protected] https://www.ietf.org/mailman/listinfo/bess
