A system, a method, and a computer program are provided for provisioning a network connectivity link to a node in a virtual private network. The method includes receiving a connectivity link change request that includes a request to change a bandwidth allocation for the network connectivity link, retrieving network connectivity information, applying the request to change the bandwidth allocation to the current bandwidth value and changing the bandwidth allocation for the connectivity link, evaluating the bandwidth values for all network connectivity links in the virtual private network, determining whether the sum of bandwidths exceeds the aggregate bandwidth value, and configuring a router with the updated bandwidth allocation to effectuate the updated bandwidth allocation in said network connectivity link.
