It provides functional description of the control plane and data plane of the virtual PE solutions. It also describes interactions among the vPE solutions and other network elements. The virtual PE solutions support further control plane and forwarding plane separation when compared with traditional L3VPN PE solutions. It allows the L3VPN functions to be extended to application end devices for large scale and efficient IP application support.
