protocol on the Layer 2 aggregate
interface

Configuring Destination Multicast MAC Address for BPDUs

By default, the destination multicast MAC address for BPDUs is 0x010F-E200-0003. You can change
it to 0x0100-0CCD-CDD0, 0x0100-0CCD-CDD1 or 0x0100-0CCD-CDD2 through the following
configuration.
Follow these steps to configure destination multicast MAC address for BPDUs:
Enter system view
Configure the destination multicast
MAC address for BPDUs
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 for STP Configuration Example

Network requirements
As shown in Figure
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 used to connect devices in the service provider network are trunk ports and allow
packets of any VLAN to pass through.
MSTP is enabled on User A's network.
