MPLS LSP Ping

This feature enables you to test and diagnose the data plane connectivity of MPLS label-switched paths (LSPs) using MPLS LSP ping. Echo requests are sent through the LSP as MPLS packets with a UDP payload, and the egress node validates the request and returns a response indicating the result. You can use MPLS LSP ping to verify LDP- or RSVP-signaled LSPs and related MPLS services, including Layer 2 circuits, Layer 2 VPNs, and Layer 3 VPNs. Probes that do not receive a response within 2 seconds are reported as failed.
