I remember a posting to this list back in the late 90s from Tony Li, who
knows a bit about BGP. He urged that multi-hop BGP never be used and
pointed out that it had not been intended for use except as a test tool,
not a production one and should have been stripped from IOS before it
was shipped.

While there are a few good cases for using it, it is generally a bad,
bad idea. And this thread demonstrates that he had reason for the warning
