Are we talking AS_Path attributes here? If so, all this means
is that now we don't announce OTHER BACKBONE routes to C&W/EXODUS,
which we probably weren't doing anyway.
Or are we talking forwarding paths, which are _different_ (and not
necessarily stable even in the presence of perfect AS_Path stability)?
If so, have we added any bottlenecks or sources of packet corruption?
If none have been added, a change in the number of links and routers
traversed is meaningless.
(Note that it is possible that the number of links and routers DECREASES).
