net

Use this command to configure the Network Entity Title (NET) that specifies the area address and the system ID for for this IS-IS router.

Syntax

net net
no net net

Parameters

net Specifies a NET for this IS-IS routing instance in the format: xx.xxxx.(...).xxxx.xxxx.xxxx.00 
where (...) indicates a variable number of xxxx area address segments.

Defaults

None.

Mode

IS-IS router configuration.

Usage

A NET is a Network Service Access Point (NSAP) address of varying length where the last byte (the NSAP-selector) is always zero. All routers within an IS-IS domain must use the same length NET. The first variable number of bytes identify the area, followed by seven fixed bytes that are divided between six bytes identifying the system ID and a single selector byte. Each router has a unique system identifier. To configure separate areas for the router, enter each area number, followed by the unique system ID for this router, followed by 00 (the NSAP-selector octet). For example: NET address 12.3333.4444.5555.6666.00 has an

  • Area of 12.3333
  • System identifier of 4444.5555.6666
  • NSAP-selector of 00

The “no” form of this command removes the configured NET for this IS-IS router.

Example

This example shows how to configure the NET with an area of 47, a system identifier of 1000.5000.0001, and a NSAP-selector of 00 for this router:

System(rw)->configure
System(rw-config)->router isis
System(rw-config-isis)->net 47.1000.5000.0001.00
System(rw-config-isis)->
