To configure destination multicast MAC address for BPDUs:
Step Command
Remarks
1.
Enter system view.

N/A
2.
Configure the destination
multicast MAC address for
BPDUs.
bpdu-tunnel tunnel-dmac
mac-address
Optional.
0x010F-E200-0003 by default.
NOTE:
For BPDUs to be recognized, the destination multicast MAC addresses configured for BPDU tunneling must
be the same on the edge devices on the service provider network.

Network requirements
As shown in
:
•
CE 1 and CE 2 are edges devices on the geographically dispersed network of User A; PE 1 and PE
2 are edge devices on the service provider network.
•
All ports that connect service provider devices and customer devices are access ports and belong
to VLAN 2. All ports that interconnect service provider devices are trunk ports and allow packets of
any VLAN to pass through.
•
MSTP is enabled on User A’s network.
After the configuration, CE 1 and CE 2 must implement consistent spanning tree calculation across the
service provider network, and the destination multicast MAC address carried in BPDUs must be
0x0100-0CCD-CDD0.
