Configuration planning is essential to organize devices in level 1, level 2 and level 1 and 2 areas. IS-IS provides defaults for basic protocol operability. Use the NFM-P to configure the IS-IS parameters. The following figure shows the IS-IS view in the navigation tree

Figure 28-7: IS-IS view

The IS-IS information that is displayed includes:

• backbone area and backbone-area devices

• a list of areas and the participating routers in each area

• a list of devices and associated interfaces that shows the IP address and the configured level (1, 2, or 1 and 2) of each interface

• the IS-IS adjacencies for each interface

The following procedures describe how to configure IS-IS.
