Thanks Paul. Localpref with Qwest on my AT&T prefixes was 100 until last week ... So my prepends to balance between the two was working just fine for the past 2 years or so. My announcements to CenturyLink to Qwest are coming out as 100.
I am not a direct customer of Qwest, so sending the community of 209:70 won¹t work (already tried that). I am a direct customer of CenturyLink and unfortunately the two networks haven¹t really come together as one just yet. I sent a note to AT&T maybe the can help do something, as I reviewed the communities with them and I am already doing what I need to do. The main problem here is that our CenturyLink connection is pure crap ... Even originating routes from their network, I had them take our AT&T (the other transit at this particular POP) - faster and less hops (go figure). At our other pops with more than 1 transits, we like to utilize both as much as possible. Contract is up in December ... can¹t wait until it¹s gone.
