configure isis area is-type level

configure isis area area_name is-type level [1 | 2 | both-1-and-2]

Description

This command configures the specified router process to operate as a level 1, level 2, or level 1/level 2 router.

Syntax Description

area_name Specifies the router process you are configuring.
level Specifies the IS-IS operation level for the router.

Default

both-1-and-2.

Usage Guidelines

Adjacencies are only formed with other routers of the same level. In addition, level 1 adjacencies are only formed with other level 1 routers with the same area address.

If there are no other L2 areas, the default is both-1-and-2. If an L2 or L1/L2 area is already present, the default is L1. This is because there can be only one L2 area in each system.

Example

The following command configures the areax router to operate at level 1:

configure isis area areax is-type level 1
