Following this thread, I have a few comments: 1. To avoid confusion, drop the text about backward compatibility with VXLAN.
2. The VXLAN-GPE draft should focus only on the VXLAN-GPE header and requires the assignment of a new UDP port. The fact that the VXLAN-GPE header closely resembles VXLAN may be convenient for implementers, but this protocol by definition is not backward compatible with VXLAN. 3. True, the 'P' bit is not needed for backward compatibility, but I'm not against it if there is value to make it consistent with the LISP-GPE header. David Melman
