Hi!
When unplugging an IPv6 node from an ethernet switchport and
plugging it back into another, the host is not reachable until
the switching table timeout expired (or any ARP timeout occurs).
Therefore, in this respect, IPv6 is not superior to IPv4.
Are there any negative consequences if an IPv6 node sends out
an unsolicitated neighbor advertisement after the link comes up
again? It might choose a random delay (e.g. up to 1 sec), but
I think this would be beneficial in hiding the ugly details of
switching tables from the user.
Or did I miss it and it is already included in some IPv6 spec?
I looked into NDP (RFC 2461) and IPv6 over Ethernet (RFC 2464).
Thanks for any info on this topic,
Walter
