Using LSP Trace

Transport LSP fault isolation is supported using the LSP trace feature. When the control plane detects a transport LSP failure, the LSR can switch to another LSP if one is available. When the failure is detected by LSP ping, you can use LSP trace to try to isolate the fault.

To start an LSP trace, use the following command:
traceroute mpls lsp [lsp_name | any host | prefix ipNetmask] {reply-mode [ip | ip-router-alert]} {{from from} {ttl ttl} {next-hop hopaddress}}
