      <abstract>
	 <t>   This document describes a method to be used by VPN Service Providers
   to provide multi-homed CEs with fast protection of egress PEs. Egress
   PEs in a redundant group always share the same label in distribution
   of VPN routes of a VRF. A virtual Next Hop (vNH) in the IGP/MPLS
   backbone is created as the common end of LSP tunnels which would
   otherwise terminate at each egress PE. Primary and backup LSP tunnels
   ended at the vNH are set up by MPLS on basis of existing IGP FRR
   mechanisms. If the primary egress PE fails, the backup egress PE can
   recognize the &quot;shared&quot; VPN route label carried by the data packets.
   Therefore, the failure affected data packets can be smoothly rerouted
   to the backup PE for delivery without changing their VPN route label.
