Re: Route table growth and hardware limits...talk to the filter

Well, how do you determine which routes to select from each provider and what to cover with defaults? How do you modify those settings once they're in place, particularly when you find exceptions in your design? I know the answers, but these are not easy questions to answer if you are a small provider that is smart enough to have multiple transit providers and enough clue to configure .* and ^$, but not enough clue to filter based upon upstream provider communities, flows and/or other dynamic means.
The whole point of BGP, to my mind, is so that I *can* accept full routes from multiple providers and *may* elect to change that behavior for other reasons. I shouldn't have to modify my BGP configuration to support my vendors' inability to provide a device that can scale to the present demands of the global routing table. Last time I checked, they are here to support me, not the other way around.
