Unless they actually want to talk to one of our customers or one of our
customers wants to talk to them.
Speaking of prepends, what's the community opinion on prepending someone
else's ASN on your routes for TE purposes if you're announcing routes you
don't want certain AS's to see, but don't have a communities knob that
works for those networks? I was pretty negative on the idea until I was
in the situation of having a working knob taken away. Nobody's
complaining about it...probably not even noticing it.
