Configuring Routing

Cisco ISA500 Series Integrated Security Appliances Administration Guide

Use the Networking > Routing > Dynamic - RIP page to configure Dynamic Routing 
or RIP. RIP is an Interior Gateway Protocol (IGP) that is commonly used in internal 
networks. It allows a router to exchange its routing information automatically with 
other routers, and allows it to dynamically adjust its routing tables and adapt to 
changes in the network.

At the top of the page, enter the following information: 

•

RIP Enable: Click On to enable RIP, or click Off to disable it. By default, RIP 
is disabled. 

•

RIP Version: If you enable RIP, specify the RIP version. The security 
appliance supports RIP Version 1 and RIP Version 2. 

-

RIP Version 1 is a class-based routing version that does not include 
subnet information. This is the most commonly supported version. 

-

RIP Version 2 includes all the functionality of RIPv1 plus it supports 
subnet information. 

-

Default: The data is sent in RIP Version 1 format and received in RIP 
Version 1 and 2 format. This is the default setting. 

In the table, specify the RIP settings for each available interface:

•

RIP Enable: Check this box to enable the RIP settings on the port or VLAN. 

•

Authentication: If you are using RIP Version 2, click the Edit (pencil) icon to 
specify the authentication method for the port or VLAN. 

-

None: Choose this option to invalidate the authentication.

-

Simple Password Authentication: Choose this option to validate the 
simple password authentication. Enter the password in the field.

-

MD5 Authentication: Choose this option to validate the MD5 
authentication. Enter the unique key ID in the MD5 Key ID field and the 
Key in the MD5 Auth Key field. 

•

Port Passive: Determines how the security appliance receives RIP packets. 
Check this box to enable this feature on the port or VLAN. 

Click Save to apply your settings.
