1.11 BPDU Tunnel Configuration Example

I. Network requirements
S3900 series switches operate as the access devices of the operator's network,
that is, Switch C and Switch D in the network diagram.
S2000 series switches operate as the access devices of the user's network, that is,
Switch A and Switch B in the network diagram.
Switch C and Switch D connect to each other through the configured trunk port of
the switch, and are enabled with the BPDU Tunnel function. Thereby transparent
transmission is realized between the user's network and the operator's network.
