Pinging RSVP-Signaled LSPs and LDP-Signaled LSPs
Enter the ping mpls command with the following syntax. Table 202 describes the ping
mpls command options.

To quit the ping mpls command, press Ctrl-C.
Alternatively, you can use the J-Web interface. (See Checking MPLS Connections from the J-Web Interface.)
