L2VPNs, or Layer 2 Virtual Private Networks, are constructed based on link level addresses. L2VPNs establish a virtual network between two or more geographically separated sites, allowing them to communicate with each other as if they were on the same physical network. This is done by encapsulating the Layer 2 traffic in Layer 3 packets, and transmitting them over the provider network. CEs (Customer Edge routers) and CR-LDPs (Constraint-based Routed LDPs) are components used in the deployment of L2VPNs, but they are not constructed based on link level addresses. L3VPNs (Layer 3 Virtual Private Networks) are constructed based on IP addresses, not link level addresses.
