Enabling BPDU tunneling for a protocol in Layer 2 aggregate interface view

Follow these steps to enable BPDU tunneling for a protocol in Layer 2 aggregate interface view:

To do…

Use the command…

Remarks

Enter system view

system-view

Enter Layer 2 aggregate interface view

interface bridge-aggregation

interface-number

Enable BPDU tunneling for a protocol

on the Layer 2 aggregate interface

bpdu-tunnel dot1q

{ cdp |

gvrp

| hgmp | pvst | stp | vtp }

Required

By default, BPDU tunneling for a

protocol is disabled.

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:

To do…

Use the command…

Remarks

Enter system view

Configure the destination multicast

MAC address for BPDUs

bpdu-tunnel tunnel-dmac

mac-address

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.
