Riverstone Networks RS Switch Router User Guide   Release 8.0   15-1

15 IS-IS CONFIGURATION GUIDE

This chapter provides an overview of the Intermediate System-Intermediate System (IS-IS) routing protocol 
features available for the Riverstone RS Switch Router. 

IS-IS is a link state hierarchical routing protocol. In IS-IS, a router is an Intermediate System (IS), and a routing 
sub domain is an area. An IS-IS area can contain a number of routers and end devices. Routing within an area is 
handled by Level 1 routers, and routing between different areas is handled by Level 2 routers. An IS can route 
Level 1 and/or Level 2 traffic.

The IS-IS routing protocol is based on “shortest path first” calculations, similar to the OSPF routing protocol. 
Intermediate Systems exchange link state information by transmitting Link State Protocol Data Units (LSPs). 
(LSPs are exchanged between same level routers only.) Each IS maintains its own LSP database. 

To configure the RS to run IS-IS, you should perform the following tasks:

•

Define the area to which the router will belong.

•

Configure IS-IS interfaces.

•

Start IS-IS.

Optionally, you can modify the default IS-IS parameters that are set globally and on a per-interface basis.

15.1 DEFINING AN IS-IS AREA

An IS-IS area is a network sub domain that consists of routers and the end devices connected to them. All routers 
in an area maintain detailed routing information about destinations within the area. When you define the area of 
the RS, all its interfaces belong to that area. Interfaces on an RS cannot belong to separate areas.

To define the IS-IS area to which the RS will belong, enter the following command in Configure mode:

15.2 CONFIGURING IS-IS INTERFACES

IS-IS is disabled on all RS interfaces by default. To  enable IS-IS on an interface,  first configure an IP interface 
using the 

interface create

 command. Then, enable IS-IS on the interface.  You can enable IS-IS on all IP 

interfaces by specifying the 

all

 

keyword. 

Defines an IS-IS area.
