Cisco has a tool called RouteM which they use for lots of BGP =
scalability testing. I used it a lot back in my testing days at UU. =
Basically you just saved the contents of "show ip route" and you could =
replay that using the tool. Man I wish I saved that tool somewhere, it =
was incredibly valuable.
You might be able find someone out there that still has this tool. And =
please get me an extra copy if you do manage to find it ;)
