I like the concept. Wording-wise, there is room for misunderstanding in the current version, 2.2.1: 2.2.1. Packet Filter Considerations The packet filter should be designed and specified in a way that: o only affect link-local BGP traffic i.e. forming part of the control plane of the system described, rather than multihop BGP which merely transits it says "link-local", but what it wants is not "fe80::" but "the prefixes the intermediate network uses for on-link peering" (plus, maybe, fe80::). So maybe "only affect *on-link* BGP traffic"? [..] > ps.
