the ~64KB MTU comes from RFC 2625 (IPv4 over Fibre Channel), and one of the goals of the IPv6 over FC specification is to keep unchanged the encapsulation technique between IPv4 and IPv6.
I understand that with IPv6 a bridge has no more the option to fragment a too big packet, as in IPv4, but I do not believe this is an issue, because:
- router advertisements may announce a proper MTU over a bridged network;
- current deployments are almost entirely based on routers instead than on bridges.
In any case, if the group believes this to be an issue, then we have the same issue also for RFC 2467 (Transmission of IPv6 Packets over FDDI Networks), where the default MTU is 4352 octets. If it is not a problem there, then it is neither a problem here.
Thanks,
Claudio.

~64KB MTU L2 media, huh? Sounds interesting.
Has there been any consideration given to L2 bridging between FiberChannel and other media such as Gbps and 10/100 Ethernet, or are you expecting everything between dissimilar media to go through a router?
