Displaying and
Debugging Integrated
IS-IS
After completing the above configuration, execute the display command in any
view to display the running state of the IS-IS configuration, and to verify the effect
of the configuration. Execute the debugging command in user view to debug the
IS-IS module.
Through the following configuration operations, you can view the LSDB of the
IS-IS, the transmitting/receiving of various packets of the IS-IS and the SPF
calculation so as to determine the IS-IS route maintenance conditions.
