Abstract
The present invention facilitates automatic discovery of VPN-related information, which relates to the existence or association of VPNs as supported by provider edge devices in a core network. In particular, the Border Gateway Protocol (BGP) is used to facilitate the automatic discovery, and the provider edge devices are capable of subsequently and automatically triggering Label Distribution Protocol (LDP) processes to facilitate signaling over LDP sessions within the core network.
