RE: [pacnog] Multihoming Problem

["Alo Anesi" <Alo.Anesi@bluesky.as>]

With the help of HPT, we've gotten the problem sorted out.
 
Here's what they see:
 
h ip bgp 202.70.112.0 
23657 23657 23657 23657 23657 23657, (received & used)     69.88.1.202 from 69.88.1.202 (202.70.114.248)       Origin IGP, localpref 100, valid, external
22026 4323 2828 25625 23657, (received & used)     64.128.3.101 from 64.128.3.101 (216.136.8.3)       Origin IGP, localpref 100, valid, external, best
 
They are seeing routes from out primary provider, AS25625, and this is what was playing havoc with my traffic engineering.
 
Thanks to everyone for their help as well. I have some new avenues to explore as a result.

In the very brief look at had at the configs, I didn't see any way that
you are consciously selecting your outbound path with local-preference
or other outbound traffic engineering mechanisms.

Maybe a show int on the (secondary provider) interface in question will
tell you if the traffic is inbound our outbound..
