Vlan-Vpn Tunnel Configuration Example - 3Com 4210 9-Port Configuration Manual

VLAN-VPN Tunnel Configuration Example

Network requirements
Switch C and Switch D are the access devices for the service provider network.
Switches 4210 operate as the access devices of the customer networks, that is, Switch A and
Switch B in the network diagram.
Switch C and Switch D are connected to each other through the configured trunk ports of the
switches. The VLAN-VPN tunnel function is enabled in system view, thus implementing
transparent transmission between the customer networks and the service provider network.
