How would you like Vendor X to liberally handle the situation? There is a point when being too liberal causes issue - like this one. The idea is that if the original peer followed the spec it would of been contained at the source and this would of never happened. Where is the line? Something about GIGO comes to mind.

I would prefer implementations (not vendors) reject the one router which they don't like, and accept the other 100,000+ routes in the global Internet without flapping BGP sessions.

Killing 100,000 routes because you don't like one seems a bit excessive.

There are only two situations where you will have a route that "isn't liked", 1) The sender does something wrong, 2) The receiver incorrectly handles something that is actually right. Either way, there is a fundamental flaw in someone's BGP implementation, and that needs to get resolved immediately. Flapping between the offender and its peer is probably an acceptable way to go about finding these, flapping over the entire internet because vendor C chooses to ignore the protocol spec and vendor F does not is probably not... -- Richard A Steenbergen <ras@e-gerbil.net> http://www.e-gerbil.net/ras PGP Key ID: 0x138EA177 (67 29 D7 BC E8 18 3E DA B2 46 B3 D8 14 36 FE B6)
