Re: AS701 peer local-pref?

I think you misunderstood the question - what you have detailed here is a 
list of customer communities that UUNet accepts, what Sean is trying to 
find out is what internal localpref UUNet sets by default - do they 
automatically give prefixes from customers a higher localpref than 
prefixes heard from peers? I don't know for sure, but I'm thinking that 
they do, which makes sense - otherwise it's possible to send traffic to a 
peer when there could be a valid path for the traffic via a customer.

Cust but not peers      701:20          propagate to custs, not peers 
keep cust routes in North America       701:30  send to custs & peers, but 
not 702, 703... 
keep AS7046 in AS701    no-export       don't propagate beyond AS701 
peers                   701:666         don't propagate beyond this AS 
peers                   701:1030        don't propagate beyond this AS

Does anyone know what local-pref AS701 sets for their customers and their
peers?  I called their NOC, and was told that is was set to 100 for both,
though I know most providers set local-pref on peers lower than customers.
I just want to get confirmation on what i was told by their NOC.

TIA.
