1.11  BPDU Tunnel Configuration Example 
I. Network requirements 
z  S5600 series switches operate as the access devices of the operator’s network, 
that is, Switch C and Switch D in the network diagram. 
z  S2000 series 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 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.
