i can see this 'attack' operational against a multihop bgp session that's not md5'd.
now the question is... would this also affect single-hop bgp sessions? my understanding would be no, as single-hops require ttl set to 1.
you can engineer packets to make sure they have the right ttl when they arrive, ie if your 10 hops away, set ttl to 10 and it will be 1 on arrival :)
Not if you use the TTL hack. Seems like that would be much more useful, and less CPU intensive, and less prone to user error, etc., etc. than MD5 -- TTFN, patrick
