Virtual Private LAN Service (VPLS) has emerged as one of the dominant MPLS applications today. Growing demand for VPLS requires the VPLS network to scale to support many VPLS customers with multiple sites spread across geographically dispersed regions. Key to scaling the VPLS network is how well the underlying VPLS control plane scales. There are two widely deployed VPLS control planes, both standardized by the Internet Engineering Task Force (IETF): one using BGP and the other using LDP. The scaling characteristics of both these control planes differ vastly. BGP VPLS signaling offers numerous advantages over LDP VPLS. Additionally, the BGP-VPLS auto discovery feature offers substantial operational benefits that have already been proven in production networks.
