Re: WG Last Call: draft-ietf-v6ops-mech-v2-01.txt

I do not see anything here that is fundamentally incompatible with the previous version
that will create interoperability issues.

I support this going to DS.

- Alain.




  -    Removed automatic tunneling and use of IPv4-compatible
        addresses.

- Removed default Configured Tunnel using IPv4 "Anycast Address"

   -    Dropped "or equal" in if (IPv4 path MTU - 20) is less than or
        equal to 1280

   -    Clarified that the dynamic path MTU mechanism in section 3.2 is
        OPTIONAL but if it is implemented it should follow the rules in
        section 3.2.

   -    Stated that when the dynamic PMTU is not implemented the sender
        MUST NOT by default send IPv6 packets larger than 1280 into the
        tunnel.

- Stated that implementations MAY have a knob by which the MTU can
be set to larger values on a tunnel by tunnel basis, but that
the default MUST be 1280 and that decapsulators need to be
configured to match the encapsulator's MTU.

- Clarified text about ingress filtering e.g. that it applies to
packet delivered to transport protocols on the decapsulator as
well as packets being forwarded by the decapsulator, and how the
decapsulator's checks help when IPv4 and IPv6 ingress filtering
is in place.
