191• Provider device—P devices do not directly connect to CEs. They only need to forward user packetsbetween PEs along the public tunnel.MPLS L2VPN network modelsMPLS L2VPN network models include remote connection model and local connection model.Remote connection modelAs shown in Figure 46, this model connects two Layer 2 customer networks over an MPLS or IP backbone.Figure 46 Remote connectionLocal connection modelAs shown in Figure 47, this model connects two Layer 2 customer networks to the same PE. The customernetworks exchange packets with each other through the PE. The PE functions like a Layer 2 switch.Figure 47 Local connectionNOTE:The switch does not support the local connection architecture.Remote connection operationRemote connection establishmentTo set up a remote MPLS L2VPN connection between two CEs over a backbone network:1. Set up a public tunnel to forward user packets from the local PE to the remote PE.The public tunnel can be an LSP, MPLS TE, or GRE tunnel. For more information about LSP andMPLS TE tunnels, see "Configuring basic MPLS" and "Configuring MPLS TE." For more informationabout GRE tunnels, see Layer 3—IP Services Configuration Guide.
