Hi Dino, Sorry, i misunderstood you. I think VXLAN-GPE can define a new UDP port and a new data format, P bit in VXLAN-GPE seems to have no any value. As for basic inter-subnet layer 3 communication and intra-subnet layer 2 communication between NVEs, current NVGRE, VXLAN and LISP have already supported, NVGRE,VXLAN,LISP and VXLAN-GPE can be hybrid used to form a NVO3 network if only basic layer 3 and layer 2 forwarding process exists. As for some extra functions of OAM, service chaining,and etc, only VXLAN-GPE can support, pure VXLAN-GPE network should be used in these cases. Thanks weiguo

I I want to make it clear that supporting backward compatibility is very important since VXLAN-port-4789 is supported in various chips already.
