Hi Valdis


Checkout routing table at NIXI and you will get idea what I am referring to
w.r.t. prepended routes.

OK. I admit being perplexed.  Under what conditions will somebody have that
many prepends and you *still* end up routing via that path if you have
another path available?

I guess if they were silly and prepended themselves 10 times and then
announced the result to the upstreams of *both* paths you have available...
