The 7210 SAS allocates one unique (platform-wide) service label per VRF. All VPN-IP routes exported by the PE from a particular VPRN service with that configuration have the same service label. When the PE receives a terminating MPLS packet, the service label value determines the VRF to which the packet belongs. A lookup of the IP packet DA in the forwarding table of the selected VRF determines the next-hop interface.
