  • Internet protocol virtual private network realization using multi-protocol label switching tunnels
    Patent number: 6205488
    Abstract: A virtual private network enables private communications between two or more private networks over a shared MPLS network. The virtual private network disclosed, includes multiple routers connected to the shared MPLS network and configured to dynamically distribute VPN information across the shared MPLS network. The VPN information distributed by a router includes a VPN identifier assigned to that router, which identifies a VPN with which that router is associated. The router includes a first table which stores a map of the label switched paths from the router in question to all other routers connected to the shared MPLS network. The router also includes a second table which stores a map of label switched paths from the router in question to all other routers connected to the shared MPLS network which share a common VPN identifier.
