They will almost always prefer their IBGP to any learned routes.  Why send
traffic to a transit network and skew their I/O peering numbers when you can
handle it yourself. I doubt you will change their mind.

Hi all,



Any Sprint BGP admins on this list can offer any thoughts on why Sprint
connected networks are preferring my Sprint connection when they should be
preferring my Verizon?



I (Healthy Directions) am AS16387, two blocks 63.73.158.0/24 and
63.78.31.0/24, being announced by sprint and Verizon, preferred to
Verizon(DS3) over Sprint 3MB.



Verizon BGP admins think everything is ok, have not heard back from BGP4 at
sprint.



Any thoughts appreciated, off-list contact welcome.



Edward
