Hi Fred, >> Are you are referring here to 'draft-nakibly-v6ops-tunnel-loop-01'?
Yes, that's correct.

Are you are referring here to 'draft-nakibly-v6ops-tunnel-loop-01'? If so, IMHO this document would be the natural location for such a recommendation. > Examples of such protocol / formats could include using a different > next-protocol value, potentially > with some multiplexing schema if just using different next-protocol values is > not scalable, or > possibly some other format. Yes, I think it would be very good to declare ip-proto-41 as fully-developed and recommend that new tunneling protocols use a different ip protocol number and/or TCP/UDP port number. This would greatly reduce the concern for having to go back and revisit tunneling implementations that perform src/dst checks if a new tunneling protocol happens to emerge. Gabi - do you have any thoughts on this?
