z 

Before configuring BPDU tunneling for a protocol, enable the protocol in the customer network 

first. 

z 

Assign the port on which you want to enable BPDU tunneling on the PE device and the connected 

port on the CE device to the same VLAN.  

z 

Configure all the ports in the service provider network as trunk ports allowing packets of any VLAN 

to pass through.  

You can enable BPDU tunneling for different protocols in different views.  

 

z 

Settings made in Ethernet interface view or Layer 2 aggregate interface view take effect only on 

the current port; settings made in port group view take effect on all ports in the port group. 

z 

Before enabling BPDU tunneling for DLDP, EOAM, GVRP, HGMP, LLDP, or STP on a port, 

disable the protocol on the port first. Because PVST is a special STP protocol, before enabling 

BPDU tunneling for PVST on a port, you need to disable STP and then enable BPDU tunneling for 

STP on the port first. 

z 

Before enabling BPDU tunneling for LACP on aggregation group member port, remove the port 

from the aggregation group first.
