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.

Optional
0x010F-E200-0003 by default.
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.
