Usage
Information
Configure a network entity title (the net command) to specify the area address and the router system
ID.
Enable routing on one or more interfaces to establish adjacencies and establish dynamic routing.
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.

Commands
● ip router isis — configure IS-IS routing processes for IP on interfaces and attaches an area designator
to the routing process.
● net — configure an IS-IS network entity title (NET) for a routing process.
● is-type — assign a type for a given area.
set-overload-bit
To set the overload bit in zeroth fragment of non-pseudonode LSPs on the router, configure the router. This setting prevents
other routers from using it as an intermediate hop in their shortest path first (SPF) calculations.
