indeed. route origin validation, while a good thing, does not make bgp safe from attack. this marketing fantasy is being propagated; but is BS. origin validation was designed to reduce the massive number of problems cause by fat figured configuration errors by operators. it will not even get all of those; but it will greatly improve things. but it provides almost zero protection against malicious attack. the attacker merely has to prepend (in the formal, not cisco display) the 'correct' origin AS to their malicious announcement. randy
