ABSTRACT:
Methods and Systems are provided for a distributed Provider Edge (PE). A single Virtual Routing and Forwarding device (VRF) is associated with a single customer site. The VRF includes a single routing table (RIB) and a single forwarding table (FIB). The VRF also includes a plurality of Virtual Private Network (VPN) Protocol Instance Modules (VRP), where each VRP is associated with a different VPN from the customer site. Each VRP accesses the RIB directly and the FIB indirectly to acquiring addressing/routing information for a received data packet. Moreover, each VRP uses a data plane of the VRP to communicate the data packets to a PE backbone device. In turn, the PE backbone device uses the data plane to communicate with each of the VRPs, and the PE backbone device communicates with one or more tunnels.
