BGP Capabilities Fill In #80

Open rcgoodfellow opened 1 year ago

rcgoodfellow commented 1 year ago

The initial set of BGP capabilities coming in #23 are fairly minimal. There are a lot of capabilities that are marked as TODO.

This issue captures how we are approaching filling in these capabilities. Note that just because a capability is deprecated does not mean it's not important. Even in my basic BGP testing thus far with FRR and Arista, deprecated options have come across the wire.

Would you mind adding this to the list as well? https://datatracker.ietf.org/doc/html/draft-abraitis-bgp-version-capability. Some other OSS implementations (FRR, GoBGP, ExaBGP, freeRtr, ...) have it already.
