On a side note, A's possibilities of influencing inbound routing decisions - given that B acts on communities set by A, like `Prepend own ASN a few times before sending over just this link' or `Don't announce to D at all' - are already technically possible. Frankly, if I were BCorrect. And a few upstreams allow this.It is very simple to do. Create a set of 'advertise-me' communities and 'pad-me' communities.
Although it did a few other things as well, an attempt at standardizing parts of this failed: draft-bonaventure-bgp-redistribution-01 This draft included: IDRP style DIST_LIST_INCL, DIST_LIST_EXCL Proxied NO_EXPORT Proxied Prepending The IDRP-style DIST_LISTs seem to generate most of the heat. We never got a firm feel for why the other two componenents were disliked. Geoff Huston proposed draft-huston-nopeer-00.txt to attempt to address some of the route propagation issues that the DIST_LISTs were intended to address.
