Periodic MPLS traceroute

The periodic MPLS traceroute function automatically traces an LSP tunnel at a specific interval. It locates errors on the LSP tunnel, verifies the consistency of the data plane and control plane, and records the detected errors into system logs. You can check the logs to monitor LSP connectivity.

If both BFD and periodic MPLS traceroute are configured for an LSP and the periodic traceroute function detects a data plane and control plane inconsistency, the device deletes the BFD session for the LSP and re-establishes the BFD session based on the control plane.
