Hi Bess, I want to implement RFC8950 but reading that document leaves me with more questionmarks then I would like.
In my case the the primary concern is to use IPv6 nexthops for SAFI 1 (unicast). Now AFI/SAFI 1/1 (IPv4 unicast) does not use MP encoding but rfc8950 requires it to use it. My questions: - Is the MP_REACH_NLRI attribute only used if the nexthop is IPv6? - What if the path is using a IPv4 nexthop, should that also use MP_REACH_NLRI or fall back to the old RFC4271 encoding using the NEXTHOP attribute? - Also what about withdraws? Are those encoded using MP_UNREACH_NLRI? - How much of a hodgepodge of encodings do we need to accept? Right now we do not accept either MP_REACH_NLRI or MP_UNREACH_NLRI for AFI/SAFI 1/1 and RFC8950 does not really explain what has to be done in this case.
