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.
To configure destination multicast MAC address for BPDUs:
Step Command Remarks
1. Enter system view. system-view N/A
2. Configure the destination
multicast MAC address for
BPDUs.
bpdu-tunnel tunnel-dmac
mac-address
Optional.
The default setting is
0x010F-E200-0003.
BPDU tunneling configuration examples
This section provides the BPDU tunneling examples.
BPDU tunneling for STP configuration example
Network requirements
As shown in Figure 30 :
• 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 connect service provider devices are trunk ports and allow packets of any
VLAN to pass through.
• MSTP is enabled on User A's network.
Configure BPDU tunneling, so that CE 1 and CE 2 implement consistent spanning tree calculation across
the service provider network, and the destination multicast MAC address carried in BPDUs is
0x0100-0CCD-CDD0.
