To verify that L2PT is working correctly, perform this task:
Verify That L2PT Is Working Correctly on page 1130
Verify That L2PT Is Working Correctly
Verify that Q-in-Q tunneling and L2PT are enabled.
Check to see that Q-in-Q tunneling and L2PT are enabled on each PE device (Switch A
and Switch D are the PE devices):
