is-typeConfigure IS-IS operating level for a router.Syntax is-type {level-1 | level-1-2 | level-2-only}To return to the default values, use the no is-type command.Parameters level-1 Allows a router to act as a Level 1 router.level-1-2 Allows a router to act as both a Level 1 and Level 2 router. This setting is the default.level-2-only Allows a router to act as a Level 2 router.Defaults level-1-2Command Modes ROUTER ISISCommand History This guide is platform-specific.

Poorly planned use of this feature may cause configuration errors, such as accidental area partitioning.If you are configuring only one area in your network, you do not need to run both Level 1 and Level 2 routingalgorithms. You can configure the IS type as Level 1.log-adjacency-changesGenerate a log messages for adjacency state changes.Syntax log-adjacency-changesTo disable this function, use the no log-adjacency-changes command.872 Intermediate System to Intermediate System (IS-IS)
