Not good, but also does not affect any other interfaces on the router.
You're assuming that all routing devices have per-interface ARP tables.
IPv6) Typically, this breaks not just on that interface, but on the entire router. This is much worse than the v4/ARP sitation.
Inverse assumption here. Doesn't change much to the case scenario you've put forward as a cause to the problem, but still wanted to point it out. Cheers, Phil
