We have a WAN network using AT&T MPLS service. Our local AS at our headend is 64000 and the MPLS AS is 13979. We propogate a default route out our headend to our remote MPLS sites via a network 0.0.0.0 statement in BGP.
We are going to be bringing on our European locations into the cloud next. They will be utilizing different AS numbers in the MPLS core (AS13980) as well as each location (AS 63000) . Their headend will be propogating out a default rout to the Europe remotes the same as we do domestically.
I want to insure that all European remote locations utilize the default route generated by their headend and the US remotes utilize the default generated by our headend. Is this something that AT&T will need to provision in the MPLS cloud, will we need to do something in our edge routers? our is it just inherent in BGP because of the different AS numbers?
