[c-nsp] Routing Problem - MCI/GT/Level3 - Puzzled

[Paul Stewart]

Yes, AS701 for us here in North America...:)  We have known that GT has a
lot of peers and have done a great job in that respect...

We're just surprised that MCI doesn't have "reach" given their sheer size in
comparison.... 

All the best,

Paul

Group telcom also has a lot of peers (i know i peer with them).   This
will result in their peers often setting a higher local-pref.

As for MCI, I am assuming you mean AS701 if you are in north-america, right?

GT is likely purchasing transit from various nets.  Those nets are likely
applying customer local-preference to GT's advertisements, and are therefore
preferring the GT path over MCI, regardless of AS path length.

Ask GT what community to use to request peer-level local-preference in their
transit providers' networks, and apply that to your announcements.

  If they don't have one, whine to GT management, and add this requirement
to all future purchasing decisions.
