The characteristic information about the Layer 2 protocol is defined, including the protocol
name, Ethernet encapsulation format and destination MAC address of Layer 2 protocol packets,
and MAC address that replaces the destination MAC address.
When defining characteristic information about a Layer 2 protocol, do not use the following
multicast MAC addresses to replace the destination MAC address of Layer 2 protocol packets:
l Destination MAC addresses of BPDUs: 0180-C200-0000 to 0180-C200-002F
l Destination MAC address of Smart Link packets: 010F-E200-0004
l Special multicast MAC addresses: 0100-0CCC-CCCC and 0100-0CCC-CCCD
l Common multicast MAC addresses that have been used on the device

11.4.3 Configuring the Transparent Transmission Mode of Layer 2
Protocol Packets
Context
To implement transparent transmission of Layer 2 protocol packets, replace the default multicast
MAC address of the Layer 2 protocol that can be identified by PEs with another multicast MAC
address or replace the original multicast destination MAC address of Layer 2 protocol packets
from user networks with a specified multicast MAC address.
Use either of the following methods on PEs according to the Layer 2 protocol type and the
required transparent transmission mode.
Procedure
l
l
Issue 01 (2011-07-15)
Replace the default multicast MAC address of the Layer 2 protocol that can be identified
by PEs with another multicast MAC address.

2. Run:
bpdu-tunnel stp bridge role provider
The PE is configured as a provider.
NOTE
l This method is applicable only to STP, RSTP, and MSTP.
Replace the original multicast MAC address of Layer 2 protocol packets from user networks
with a specified multicast MAC address.
