Hi Sri, Adding GRE support to Mobile IPv6 needs a bit more than a pointer to the GRE spec. Quoting from the IESG ballot: - There's no text describing how GRE tunneling is actually done; for example, how the various parts of GRE header are set/used in the context of Mobile IPv6, how that interacts with RFC 4877, etc. Also, the whole 'T' bit is problematic; from the IESG ballot: - Apparently the 'T' bit does means only that MN supports the general TLV format; it may not support any of the specific TLV types, such as GRE (and new ones may be defined in the future). How this is supposed to work?
