> AS3128 runs MPLS and it's probable someone might correct me here, but for a IGP backbone area I think it's common for there to be a full mesh of LSPs via either LDP, RSVP, SR etc.  AS3128 is a small regional and we operate in that way across 60+ nodes.  I don't know if it's common for someone with a global footprint like 1299 to have a contiguous global MPLS backbone, but the point of my reply was to say it's not impossible to think 1299 has a global MPLS mesh between major POPs.

Yes, this is the common case, not an exception.
