is-type
Use this command to set the IS to the specified level of routing.
Changing is-type brings down, then brings up a particular level of routing. There is a limitation: Only one ISIS instance can run Level-2 routing (either Level-2 only IS, or Level-1-2 IS).
Use the no parameter to set the IS to the default.
