Description
Use the vlan-vpn tunnel command to enable the VLAN-VPN tunnel function for a
switch.
Use the undo vlan-vpn tunnel command to disable the VLAN-VPN tunnel function.
The VLAN-VPN tunnel function enables BPDUs to be transparently transmitted
between geographically dispersed user networks through specified VLAN VPNs in
operator’s networks, through which spanning trees can be generated across these user
networks and are independent of those of the operator’s network.
By default, the VLAN-VPN tunnel function is disabled.
Note:
z The VLAN-VPN tunnel function can only be enabled on STP-enabled devices.
z To enable the VLAN-VPN function, make sure the links between operator’s
networks are trunk links.
