IMHO, overloading the BGP community field is not the appropiate place for such inter-domain policy publication. Not only is the BGP community field only 32 bit (thus not allowing for targetting 32 bit ASNs with an action) - it will never provide a uniform interface for users as each AS interprets and treats communities in their own way. > However, some people have commented that the community field cannot be > used for this purpose with 32-bit AS Numbers.

Also, I feel that we should be careful in this thread not to venture into a zealotic discussion what the best approach is (BGP Communities versus RPSL), but rather discuss if RPSL-via is valid and workable, and if yes allow people to use it.
