Abstract
A virtual private network infrastructure is provided which enables private network communications over a shared network. The infrastructure includes a shared network partitioned into at least two separate areas. A first router is connected to a first area and configured to distribute first router VPN information across the first area. The first router VPN information includes a VPN identifier which is assigned to the first router. It also includes a second router connected between the first area and a second area which is configured to distribute second router VPN information across the first area. The second router VPN information includes a VPN identifier which is assigned to the second router which is the same VPN identifier assigned to the first router.A method of configuring a virtual private network infrastructure is also provided which enables private network communications over a shared network. The method includes partitioning a shared network into multiple areas and connecting a virtual router between at least two of the areas. A VPN identifier is assigned to the virtual router. A link is created between a first private network router and a first shared network router whi…
