I think you meant to say not all "paths" are equal. Routes are routes.
Where they lead to is another matter.

The presence of a PNI does not preclude good governance of an exchange
point link. If you are going to (willingly or otherwise) ignore the
health of your public peering links over your private ones (or vice
versa), then I wish upon you all the hell you'll face that comes with
taking that position.

Our policy is simple - 50% utilized, you upgrade. Doesn't matter what
type of link it is; WDM Transport, IP, peering (public or private),
Metro, core backbone, protection paths, e.t.c. Choosing to let your
public peering links run hot because your "major" peers are taken care
of by the private links is irresponsible. Do a lot of networks do it;
hell yes, and for reasons you'd not think are obvious.

Agreed, but that's not the crux of this thread (even though it's one of
the reasons we do not relay solely on RS's).

Mark.
