I've also thought that if routers could filter based on lookup up source addresses in a BGP-made RIB, rather than just destination addresses, that the whole filtering-by-remote-control industry would appreciate the hell out of it. I'm pretty sure that both the 12016 and M160 have the hardware it would take to do this at wire speed, but I'm also pretty sure that the market for this feature is perceived by both vendors as "small."

Paul I'm pretty sure we're not the only ones who have been asking for this. A dedicated protocol for managing filters would be even nicer, but perhaps a little too difficult to put together. Actually I think you might be very close to being able to put something like this together with some of Juniper's policying routing features, with either slight changes or upcoming software features. Congratulations to those who created an ASIC with enough functionality and generic design to do these kind of things. -- Richard A Steenbergen <ras@e-gerbil.net> http://www.e-gerbil.net/humble PGP Key ID: 0x138EA177 (67 29 D7 BC E8 18 3E DA B2 46 B3 D8 14 36 FE B6)
