Step 4 Configure PEs to replace the destination MAC address of STP packets received from CEs.
# Configure PE1.
[PE1] l2protocol-tunnel stp group-mac 0100-5e00-0011
# Configure PE2.
[PE2] l2protocol-tunnel stp group-mac 0100-5e00-0011
Step 5 Verify the configuration.
After the configuration, run the display l2protocol-tunnel group-mac command. You can view
the protocol type or name, original destination MAC address, new destination MAC address,
and priority of Layer 2 protocol packets to be transparently transmitted.
Take the output on PE1 as an example.

Run the display stp command on CE1 and CE2 to view the root in the MST region. You can
find that a spanning tree is calculated between CE1 and CE2. GE 1/0/0 of CE1 is a root port,
and CE 1/0/0 of CE2 is a designated port.
