Usage Scenario
You can change the priority of BFD packets in the following scenarios:
Detect whether packets with different priorities on a link can be forwarded.
Ensure that BFD packets with a higher priority are forwarded first.
Precautions
When congestion occurs, the system first sends BFD packets with a higher priority.
The tos-exp command takes effect for only static BFD sessions.
