■

The STP protocol must be enabled on those devices that have enabled BPDU 
TUNNEL; otherwise after BPDUs of the client network enter the switch, they 
will not be processed by the CPU, so their MAC addresses cannot be replaced, 
that is to say, they cannot be transparently transported.

■

The port that has enabled VLAN-VPN must be configured as the access port; 
the intermediate operator network must be configured as trunk link;

■

BPDU TUNNEL cannot be configured on ports that have enabled DOT1X, GVRP, 
GMRP, STP and NTDP protocols.
