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.
I see you're prepending the heck out of your announcement to Sprint...but Sprint is apparently still prefering to use their internal/customer route to you rather than send your traffic across the internet. If you really want Sprint to not use your 3MB circuit unless the Verizon one is down, have a look at https://www.sprint.net/index.php?p=policy_bgp You probably want to lower their localpref for your routes. ---------------------------------------------------------------------- Jon Lewis | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
