VLAN transparency configuration example

As shown in Figure 117, the trunk interfaces of Switch A and Switch B are assigned to the same VLAN.

Enable VLAN transparency on interfaces Ethernet 1/1 and ATM 5/0 on both Router A and Router B so the two office areas can communicate within the same VLAN.

1. Configure Router A:

   # Enable the bridging function.

   <RouterA> system-view
   [RouterA] bridge enable
   [RouterA] bridge 2 enable
   

   # Add Ethernet 1/1 to bridge set 2 and enable VLAN transparency on Ethernet 1/1. Add ATM 5/0 to bridge-set 2 and enable VLAN transparency.

   [RouterA] interface ethernet 1/1
   [RouterA-Ethernet1/1] bridge-set 2
   [RouterA-Ethernet1/1] bridge vlanid-transparent-transmit enable
   [RouterA-Ethernet1/1] quit
   [RouterA] interface atm5/0
   [RouterA-Atm5/0] bridge-set 2
   [RouterA-Atm5/0] bridge vlanid-transparent-transmit enable
   [RouterA-Atm5/0] pvc to_r2 1/100
   [RouterA-Atm5/0-1/100-to_r2] map bridge-group broadcast
   

2. Configure Router B:

   # Enable the bridging function.

   <RouterB> system-view
   [RouterB] bridge enable
   [RouterB] bridge 2 enable
   

   # Add Ethernet 1/1 to bridge set 2 and enable VLAN transparency on Ethernet 1/1. Add ATM 5/0 to bridge-set 2 and enable VLAN transparency.

   [RouterA] interface ethernet 1/1
   [RouterB-Ethernet1/1] bridge-set 2
   [RouterB-Ethernet1/1] bridge vlanid-transparent-transmit enable
   [RouterB-Ethernet1/1] quit
   [RouterB] interface atm5/0
   [RouterB-Atm5/0] bridge-set 2
   [RouterB-Atm5/0] bridge vlanid-transparent-transmit enable
   [RouterB-Atm5/0] pvc to_r1 1/100
   [RouterB-Atm5/0-1/100-to_r1] map bridge-group broadcast
