2.3 BPDU Tunnel Configuration Example
I. Network requirements
z
Custimer1 and Customer2 are access devices operating in a user network.
z
Provider1 and Provider2 are access devices operating in the operator’s network.
They are interconnected through their trunk ports, as shown in Figure 2-4.
z
Enable the BPDU Tunnel function for NDP packets on the Ethernet1/0/1 and
Ethernet1/0/4 port shown in the Figure 2-4.Set the port Ethernet1/0/2 and
Ethernet1/0/3 to be BPDU Tunnel uplink ports.
