Hi, Bryce! Is this what you are looking for? https://www.iana.org/assignments/bgp-well-known-communities/bgp-well-known-communities.xhtml https://tools.ietf.org/html/rfc1997 Best regards, João Butzke. Em 11/11/2018 22:57, Bryce Wilson escreveu:
I’m working on updating the BGP communities that are processed and used in my routers and I was interested as to what some of the common BGP communities that I might want to implement parsing for might be.As I understand it, it is somewhat required that no export, no advertise and no export subconfed are implemented. I believe that there is also a no peer option which asks that a prefix not be announced over a peering relationship, only transit and downstream.I do have my own informational prefixes for source location and peering vs transit prefixes so it would not be a stretch to add a version to allow for restrictions on where a prefix is announced and possibly prepending as well. I am aware that action communities exist for blackhole and setting of local preference but I can not find a consensus as to what those communities may be.Thanks ~ Bryce Wilson, AS202313, EVIX, AS137933
