Dear all, We have submitted a new draft: Label Sharing for Fast PE Protection.
This draft designs a simple method to be used by SPs to achieve fast PE protection, utilizing the deployment of redundant egress PEs. Comments are welcome.

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 and deliver the failure affected packets accordingly. The IETF Secretariat
