Weiguo, There are already implementations using value 10 in the RFC5512 BGP encap ext community. That is the value you would have in RFC7432 compliant networks where you can also have overlay tunnels. Value 10 would indicate to the ingress PE that the route needs an MPLS tunnel to be resolved.

In section 13 IANA considerations, several overlay tunnel types are requested as follows: 8 VXLAN Encapsulation 9 NVGRE Encapsulation 10 MPLS Encapsulation (?) 11 MPLS in GRE Encapsulation 12 VXLAN GPE Encapsulation IMO, 8,9,11 and 12 are all overlay encapsulations, 10 is an exception. Would you like to explain what's the purpose of tunnel type 10? Thanks, weiguo
