that would also be a significant change in the IPv6 architecture. IPv6 over IPv6 tunnels do outer fragmentation today (RFC2473) and tunnel egress must perform reassembly. cheers, Ole -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
