Hi Paul, I read this draft. Both this draft and our draft http://datatracker.ietf.org/doc/draft-yong-l3vpn-nvgre-vxlan-encap/ propose adding prototype type field in VXLAN header in supporting L3 overlays (or other) beside L2 overlays. The only difference between two is that this draft requests using P bit to indicate the presence of protocol type field in VXLAN header. We don't think this is necessary. For the backward compatibility, we propose treating protocol type value 0 as Ethernet payload.
This draft gives two ways to do L2 overlay. If P bit is set and protocol type value 0x6558, L2 payload is follow, or P bit is unset, L2 payload is follow. IMHO, this is bad.
