Quick poll: does any operator here currently use a router which does
not support setting BGP community attributes, does not permit community
attributes to be matched exactly when doing ingress/egress route
filtering, or does not permit wildcard matches on the last two octets
(e.g. "permit 1234:*")?
If any of those statements apply to a BGP implementation you have used,
could you let me know? Off-list is fine. I can summarise the results if
there is interest.
