2.4.2 Displaying and Debugging LDP

I. LDP display commands
V 2.41 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.
