Abstract
A computer system includes functionality enabling a provider edge router to determine whether network data such as VRF information is properly associated with a corresponding virtual private network. A first node through which the network data is transmitted generates a signature value uniquely associated with the virtual private network. The first node forwards the signature value along with the network data to a second node of the physical network. The second node, in turn, verifies that the network data (such as VRF information) is properly associated with the second node (and virtual network) based on its own generation of a signature value, which is compared with the signature value received from the first node.
