Could anyone tell me if this scenario would be possible and point me in the right direction in order to research the topic?
Is it possible for a hosting company to order a single Layer 3 MPLS-VPN circuit from a provider (Sprint) and have themselves added as a node on the MPLS network of multiple clients (Client A & Client B), as long as they used the same provider as well? The hosting company would like to save money with a single circuit, instead of bringing in a circuit for each client. I realize that there would have to be configuration on the end of the provider, if this was even possible.
If is is possible to be on multiple MPLS networks from one circuit, how would you keep the routing tables separate from each other?
