Rather than dropping those ICMP PTB, let's accept them but let the OS decide which is the minimum size path MTU that it can accept/tolerate... - For a server, this min path MTU should be large (to avoid DoS) - For a host, this min path MTU could be small
Of course, if the path is symmetric, the path MTU will be the same on both direction (assuming everything is well configured). OTOH, as written by Jared, let's fail it hard so it is noticeable by the user is another technique... but with a dual-stack and happy eye-ball, the end-user will notice nothing and will stay happy with IPv4. -éric -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
