This command configures the specified router process to operate as a level 1, level 2, or level 1/level 2 router.
|area_name||Specifies the router process you are configuring.|
|level||Specifies the IS-IS operation level for the router.|
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.
The following command configures the areax router to operate at level 1:
configure isis area areax is-type level 1
