Network requirementsz Switch C and Switch D operate as the access devices of the operator’s network, inthe network diagram.z S3100-SI switches operate as the access devices of the user’s network, that is,Switch A and Switch B in the network diagram.z Switch C and Switch D are connected to each other through the configured trunkports of the switches. The VLAN-VPN tunnel function is enabled in system view,thus implementing transparent transmission between the user’s network and theoperator’s network.
