        Simply put, yes.  Longer answer, Level(3) would have to "kiss
and make up" with Cogent before the sessions would be coordinated to
be turned up.  There would certainly have to be a renewed level of
communication between these two networks to come up with this result.

        Well, there are three options here.

        ->  Both networks kiss and make up, ending up turning up
the pre-existing peering session, or possibly additional peering
sessions.

        -> Cogent obtains transit from another provider to Level(3).

        -> Level(3) obtains transit from another provider to Cogent.

        Business decisions do not always make sense, stubbornness can
very easily get in the way of a proper decison[1].
