Abstract:
This document describes a method to be used by Service Providers to
provide fast protection of VPN connections for a CE. Egress PEs in a
redundant group always assign the same label for VPN routes from a
VRF. These egress PEs create a BGP virtual Next Hop (vNH) in the
domain of the IP/MPLS backbone network as an agent of the CE router.
Primary and backup tunnels terminated at the vNH are set up by the
BGP/MPLS IP VPN based on IGP FRR. If the primary egress PE fails, the
backup egress PEs can recognize the "shared" VPN route label, so that
the failure affected traffic can be smoothly switched to the backup
PE for delivery without changing its VPN route label.
