No. Not a new Ethertype - we are talking about MPLS NOT Ethernet. There is a protocol type (it's actually called a "channel type") in the Ach control word. See RFC 4385. Right now only a few are defined (raw BFD, IPv4, IPv6).

New protocol type on what level? Ethernet, so this would involve a new ethertype? If routers generally can look that far into the packet on the correct forwarding level (I doubt it though) then that would be the least intrusive, but having LSRs look for ethertype within MPLS labeled packets sounds kind of advanced to do that early in the receive path? Why not do it more like an MPLS L3 VPN terminated/routed by all involved&&aware routers, then it would signal special labels to its neighbours that would be local significance only? But now we're talking handling it like a tree and that would involve routing protocols as well... Basically this would be like multicast IP and could leverage all the multicast MPLS standards out there. -- Mikael Abrahamsson email: [email protected] _______________________________________________ TICTOC mailing list [email protected] https://www.ietf.org/mailman/listinfo/tictoc
