Step 6 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 ouput on PE1 as an example.
<PE1> display l2protocol-tunnel group-mac stp

ssap 0x42
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.
