Without that MD5 checksum you are quite vulnerable to that. I haven't seen a vendor come up with a solution to that, because the problem is on a much more vendor-neutral level... Have you actually done the work to see how many packets it takes to shut down a session with and without MD5 enabled? (The question is rhetorical, since your post shows that you have not.) Back on topic, the MD5 debate is not an exact apples-to-apples comparison of BCP38. Stopping people from shutting down your BGP sessions is not the same as letting your customer hurt me while claiming to be a third party. Put another way, MD5 on BGP sessions is a personal choice per network. I made my decision. You are welcome and encouraged to make your own. Neither will effect the other, except where our two networks meet. (And then I am positive we can come to some mutual understanding.) BCP38 is not a personal decision. Not implementing it hurts the whole Internet, not just your little corner. -- TTFN, patrick
