level-2: Configures the router to work on Level-2, which means it calculates routes and maintains the 

LSDB for L2 only.  

Use the is-level command to specify the IS level.  

Use the undo is-level command to restore the default.  

The default IS level is level-1-2.  

You can configure all the routers as either Level-1 or Level-2 if there is only one area, because there is 

no need for all routers to maintain two identical databases at the same time. If the only area is an IP 

network, you are recommended to configure all the routers as Level-2 for scalability.  

Related commands: isis circuit-level.
