By default, for Cisco devices, the MPLS Topology Server includes the following command options in the LSP ping command lines that it constructs and invokes for LSP ping server tool invocations:
ping mpls ipv4 <destination-address destination-mask> [repeat 5] [timeout 2] [size 100] [interval 0]
Here is an example of an LSP ping command line and the ping test results. The remote computer shell prompt “Router#” indicates that the MPLS Topology Server has established a Telnet, SSH1, or SSH2 session with the originating device.
