Monitoring IS-IS

To monitor the IS-IS tables and databases, use the following commands in EXEC mode, as needed:

Command	Purpose

Router# show isis database [level-1]	Displays the IS-IS link-state database.
[level-2] [l1] [l2] [detail] [lspid]

Router# show isis area-tagroutes	Displays the IS-IS Level 1 routing table.

Router# show isis spf-log	Displays how often and why the router has run a full SPF calculation.

Router# show isis area-tagtopology	Displays a list of all connected routers in all areas.

IS-IS Configuration Examples

This section includes the following examples:

•Enabling IS-IS Configuration Example

•Multiarea IS-IS Configuration for CLNS Network Example

•IS-IS Throttle Timers Example

Enabling IS-IS Configuration Example

The following example shows how to configure three routers to run IS-IS as an IP routing protocol. Figure 53 illustrates the example configuration.
