Quickie comment: the CIDR/prefix length filter appears to be incompatible with IPv6, and cannot really be expanded to handle it. And to a more generic comment.. I have a cornern whether this would really solve the needs which route redistribution now has; basically the impression is that this is a way of standardizing non-transitive redistribution community values. Good. But the question is, are transitive communities (or at least, ones that are passed downs at least one more hop from your peer) being used for controlling redistribution? I could imagine that if we would consider a simple model: Small-ISP --> Large-ISP --> International-Transit --> Some-ISP --> (The reality is surely more multilayered.) Currently the proposed mechanism allows to influence how Large-ISP redistributes the routes. However, I could imagine some, even many (especially if a goal is standardize redistribution values) might want to be able to influence the redistribution e.g. one or two more hops upstream. So in conclusion, my worry is whether this addresses significant enough part of the redistribution problem. -- Pekka Savola "Tell me of difficulties surmounted, Netcore Oy not those you stumble over and fall" Systems.
