I am not sure this is possible, but I'd like to route traffic over an MPLS network using BGP to different locations, but use the same subnet.
We have an east coast and west coast location. Each of these locations has a VPN connection to a common 3rd party location via VPN. The subnet of this 3rd party is 10.5.5.0/24. We have a number of locations throughout the United States all connected through an MPLS network. I would like those locations to use either the east or west coast VPN.
How could I route some traffic to 10.5.5.0/24 in one location and some to the other? I read it might be possible using different AS numbers and one would need to coordinate this with the MPLS provider, but really not sure.
Any ideas? If you need more detail please let me know. I am not a network engineer by trade and really just hack my way through this stuff.
