ABSTRACT:
A system and method for transmitting data from a first site to a second site over a shared Multi-Protocol Label Switched (MPLS) network comprising a plurality of routers, including an ingress router in communication with the first site and an egress router in communication with the second site, includes configuring a plurality of label switching paths between the ingress router and the egress router over a plurality of label switching devices. The method further includes performing a first lookup on one of at least one virtual routing and forwarding (VRF) table stored in the ingress router, whereby the first lookup identifies one routing table from a plurality of routing tables stored in the ingress router, each routing table being associated with one of the plurality of label switched paths, and performing a second lookup on the one routing table, wherein the routing table defines the associated label switched path between the ingress router and the egress router for a virtual private network (VPN) between the first site and the second site.
