Description
Use the vlan-vpn tunnel command to enable bridge protocol data unit (BPDU)
Tunnel on the switch.
Use the undo vlan-vpn tunnel command to disable BPDU Tunnel on the switch.
BPDU Tunnel enables geographically segmented user network to transmit BPDU
packets transparently over the specified VLAN VPN on the operator’s network. This
allows the user network to participate in a uniform spanning tree calculation while
maintaining a separate spanning tree from the operator network.
By default, BPDU Tunnel is disabled.
 Note:
z Be sure to enable STP for network devices that are BPDU TUNNEL-enabled.
z Be sure to configure the ports that are BPDU TUNNEL-enabled to be Access
ports.
z Configure Trunk links between operator’s networks.
z Do not enable the BPDU TUNNEL function for ports that have 802.1x, GVRP,
GMRP, STP, or NTDP enabled.
