2.4.2 Displaying and Debugging LDP

I. LDP display commands
The H3C S9500 provides abundant MPLS monitoring commands for monitoring states
of LSRs, LDP sessions, interfaces and peers. These commands are the powerful
debugging and diagnosing tools.
After accomplishing the configuration tasks described earlier, you can execute the
display command in any view to view the running state of LDP and thus to evaluate the
effect of the configurations.
