I assume its still in WIP, but make sure the unit tests are not nulled out before merging :)

hah, nice, thanks for pointing that out

while testing against BIRD, we found out that if one doesn't explicitly request -protocol 2, then after BIRD sends Serial Query with verson set to 2, StayRTR replies with Cache Response but version set to 1

supposing that both sides are violating the draft here, section 7, because in this case, StayRTR should either accept version 2, or send Error Report with code 4, and BIRD should, after receiving a different version, probably drop the session as well

I wanna revisit this PR in the context of a completed 8210bis if that sounds good. Because we want all that ASPA shit and blahblah.

I suspect draft-8210bis is now stable and we should implement asap. If we complete the work before WGLC, any feedback we may have still is valuable
