MPLS L2VPN network models
MPLS L2VPN network models include remote connection model and local connection model.
Remote connection model

PE. The customer networks exchange packets with each other through the PE. The PE functions like a Layer
2 switch.

NOTE:
This switch series does not support the local connection model.
Remote connection operation
Remote connection establishement
To set up a remote MPLS L2VPN connection between two CEs over a backbone network:
Set up a public tunnel to forward user packets from the local PE to the remote PE.
