Patent abstract

A management system manages multiple multi-protocol label switching (MPLS) virtual private networks (VPNs), the VPNs having overlapping IP addresses. The system includes a storage storing a file that associates a host name with an IP address and a route distinguisher. The host name corresponds to a network element within one of the customer VPNs. The system also includes a label obtaining system that obtains at least one label for the host name based upon the associated IP address and route distinguisher. The system also has a packet construction system that creates packets destined for the network element using the obtained label(s).
