Name

net — router, IS-IS

Synopsis

net value
no net value

Configures

The NET for an IS-IS routing process

Default

None

Description

In order to configure an IS-IS routing process, you need to define a Network Entity Title (NET). Essentially, a NET serves as the area number and the system ID for the routing process. The NET is an NSAP whose last byte is 0.

Example

Let’s assume that we have an IS-IS system ID of 0000.0000.0004 and an area ID of 04.0002. This gives us a NET of 04.0002.0000.0000.0004.00, which is the area ID followed by the system ID followed by the ending zero. The following configuration shows how the net command is used to assign the appropriate value:

router isis
  net 04.0002.0000.0000.0004.00
  is-type level-1
!
interface ethernet 0
  ip router isis
  ip address 10.1.1.1 255.255.255.0
