Large communities indicating RPKI VALID status

[Maria Matejka]

Hello Nigel,

you can always store this information to custom attributes which are faster than communities, auto-ignored on export and can't leak to your peers.

BTW that guide looks quite outdated (regarding e.g. the support of autoreload) and will be even more outdated with BIRD 3 optimized import tables and selective autoreload. Noting that we shall look into updating this guide.
