Pinging an MPLS LSP Endpoint

To determine whether an LSP between two provider edge (PE) routers is up and running, you can ping the endpoint address of the LSP. The command you use to ping an MPLS LSP endpoint is ping mpls lsp-end-point address. This command tells you what type of LSP (RSVP or LDP) terminates at the address specified and whether that LSP is up or down.

For a detailed description of this command, see the JUNOS Protocols, Class of Service, and System Basics Command Reference.
