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.
