VLAN-VPN tunneling enables BPDUs to be transparently transmitted between 
geographically dispersed customer networks through a specific VLAN VPN over 
the service provider network. This allows the customer networks to share a 
spanning tree independent of that of the service provider network.

Figure 23   Network diagram for VLAN-VPN tunneling configuration

 

■

Use the Switch 5500 (Switch C and Switch D in the network diagram) as access 
devices of the service provider network.

■

Use the Switch 4210 (Switch A and Switch B in the network diagram) as access 
devices of the customer networks.

■

Connect Switch C and Switch D through trunk ports. Enable VLAN-VPN 
tunneling in system view to achieve transparent transmission between the 
customer networks over the service provider network.
