Overview
MPLS Operation, Administration and Maintenance (OAM) provides fault management tools for MPLS data plane connectivity verification, data plane and control plane consistency verification, and fault locating. These fault management tools include the following types:
On-demand tools—Tools that need to be triggered manually, such as MPLS ping and MPLS traceroute.
Proactive tools—Tools that are triggered by the system automatically, such as MPLS BFD and periodic MPLS traceroute.
You can use these tools to detect and locate faults of LSPs, MPLS TE tunnels, and MPLS PWs.
