1.11 BPDU Tunnel Configuration Example
I. Network requirements
z
S3100-52P Ethernet 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 are connected to each other through the configured trunk
ports of the switches. The BPDU Tunnel function is enabled in system view, thus
implementing transparent transmission between the user’s network and the
operator’s network.

III. Configuration procedure
1) Configure Switch A
# Enable RSTP.
<H3C> system-view
[H3C] stp enable
# Add Ethernet 0/1 to VLAN 10.
[H3C] vlan 10
[H3C-Vlan10] port Ethernet 0/1
2) Configure Switch B
# Enable RSTP.
<H3C> system-view
[H3C] stp enable
# Add Ethernet 0/1 to VLAN 10.
