Release Information

Statement introduced before JUNOS Release 7.4.

Description

Disable IS-IS on the router, on an interface, or on a level. At the [edit protocols isis traffic-engineering] hierarchy level, disable IS-IS support for traffic engineering.

Enabling IS-IS on an interface (by including the interface statement at the [edit protocols isis] or the [edit routing-instances routing-instance-name protocols isis] hierarchy level), disabling it (by including the disable statement), and not actually having IS-IS run on an interface (by including the passive statement) are mutually exclusive states.

Default

IS-IS is enabled for Level 1 and Level 2 routers on all interfaces on which an International Organization of Standardization (ISO) protocol family is enabled.

IS-IS support for traffic engineering is enabled.

Usage Guidelines

See IS-IS Overview, Disabling IS-IS Support for Traffic Engineering, and Disabling IS-IS.
