If that comes to pass, then the fix will be useless, unfortunately, just as=
dynamic ARP inspection (DAI) is useless today; it self-DoSes the box.
Any form of 'inspection' will not scale for this problem, as it will be CPU=

All this ICMPv6 weirdness and outright brokenness is the Achilles' heel of =
IPv6, and I see no ready solution in sight for the set of problems it engen=
