L3VPN: BGP/MPLS VPNs using MPLS backbone The L3VPN protocol implements RFC 4364 BGP/MPLS VPNs using MPLS backbone. It works similarly to pipe. It connects IP table (one per VRF) with (global) VPN table. Routes passed from VPN table to IP table are stripped of RD and filtered by import targets, routes passed in the other direction are extended with RD, MPLS labels and export targets in extended communities. A separate MPLS channel is used to announce MPLS routes for the labels.
