Data corruption in a BGP update packet with a long AS_PATH using the as-path-prepend option, could cause the a neighboring eBGP peer to drop the session with an update message error. The number of AS_PATH prepends are excessive (greater than 254), but can happen through normal operational configuration. Given the nature of AS_PATH, the as-path-prepend can be crafted to impact routers several AS hops away from the origin.
