Hi, In "6.2. End.M.GTP6.D", how would SR Gateway know if user packet inside GTP is IPv4 or IPv6? I think this info is required to set newly added SRH.NextHeader field in step 3~5.
My understanding is that information would be provided by the control plane, and if that's correct, should SR Gateway have 2 (or more) SIDs corresponding to the type of user packet and also inform gNB to use different SIDs (dstAddr) based on user packet type? One could also have SID per TEID, but I'm not sure if that's a good design choice considering the effort to reduce state in network nodes.
