Configure the destination
multicast MAC address for BPDUs
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.

BPDU tunneling configuration examples

BPDU tunneling for STP configuration example

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.
