In this example, PEs on the backbone network transparently transmit STP packets sent from CEs
by replacing the original multicast destination MAC address of STP packets with a specified
MAC address. By default, the destination MAC address of STP packets is 0180-C200-0000.

Configuration Roadmap
The configuration roadmap is as follows:
1. Configure STP on CEs.
2. Add user-side interfaces of PEs to the specified VLANs.
3. Configure interface-based Layer 2 protocol transparent transmission on PEs.
4. Configure network-side interfaces of PEs to allow packets of VLAN 100 and VLAN 200
to pass.
Data Preparation
To complete the configuration, you need the following data:
l IDs of VLANs that user-side interfaces of PEs belong to
l IDs of VLANs allowed by network-side interfaces of PEs
Procedure
Step 1 Enable STP on CEs and PEs.
# Configure CE1.
