This chapter covers the following topics, which you need to understand to pass the CCNP/CCDP/CCIP BSCI exam:
Basic configuration of Integrated IS-IS
Optional Integrated IS-IS commands
Verifying the Integrated IS-IS operation
Troubleshooting the Integrated IS-IS operation
As in all configurations, the essential commands give a basic configuration, and the more advanced commands either tune the system for efficiency or provide additional configurations for different situations. There is the cake, and then there is the icing. The first section of this chapter deals with the required commands. The next section covers the optional commands. You then learn how to confirm the configuration and how to troubleshoot that configuration to maintain the smooth operation of the network.
