level-1: Configures the router to work on Level-1, which means it only calculates 
routes within the area, and maintains the L1 LSDB.

level-1-2: Configures the router to work on Level-1-2, which means it calculates 
routes and maintains the LSDBs for both L1 and L2.

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 configure IS-IS router type.

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

The default router type is level-1-2.

It is recommended to configure system level when you configure IS-IS.

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. In this case, you are recommended to configure all the routers as 
Level-2 in the IP network for scalability consideration.

# Configure the router to work in Level-1.

Use the is-name command to enable the dynamic hostname process and 
configure a name for the router, which is advertised in an LSP.

Use the undo is-name command to remove the configuration.

No IS name is configured by default.
