MPLS L2VPN network models
MPLS L2VPN network models include remote connection model and local connection model.
Remote connection model
As shown in Figure 35, this model connects two Layer 2 customer networks over an MPLS or IP backbone.
Figure 35 Remote connection
Local connection model
As shown in Figure 36, this model connects two Layer 2 customer networks to the same PE. The customer
networks exchange packets with each other through the PE. The PE functions like a Layer 2 switch.

To 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 and
MPLS TE tunnels, see "Configuring basic MPLS" and "Configuring MPLS TE." For more information
about GRE tunnels, see Layer 3—IP Services Configuration Guide.
If multiple public tunnels exist between two PEs, you can configure a tunneling policy to control
tunnel selection. For more information about tunneling policy, see "Configuring MPLS L3VPN."
2. Set up a VC to identify customer networks.
