A system and method collects information for VPN traffic from non edge routers that are coupled to edge routers and identifies the path the traffic took and the customer corresponding to the VPN. The system and method also identifies the ingress router coupled to the non edge router from which the traffic was collected. The system and method may assign identifiers to route targets.
