Usage
Information
Configure a network entity title (the net command) to specify the area address and the router system
ID.
To establish adjacencies and establish dynamic routing, enable routing on one or more interfaces.
You can configure only one IS-IS routing process to perform Level 2 routing. A level-1-2 designation
performs Level 1 and Level 2 routing at the same time.
