RIP Interface Parameters Overview

By default, RIP is disabled on all interfaces in the VR. You must enable RIP on an interface before RIP can use that interface to transmit receive packets. When you disable RIP on an interface, RIP does not transmit or receive packets on the specified interface, but interface configuration parameters are preserved.

For instructions for configuring RIP settings on the virtual router and on the interface, see the Network and Security Manager Online Help.

You can enable RIP on ethernet and tunnel interfaces. When configuring RIP on a tunnel interface, you can configure additional parameters to keep RIP tunnel traffic to a minimum.

You can configure the following RIP interface parameters:

Configuring RIP Authentication

Because RIP packets are unencrypted, most protocol analyzers can decapsulate them. Authenticating RIP neighbors using MD5 authentication or simple password is the best way to fend off these types of attacks. When authentication is enabled, the device discards all unauthenticated RIP packets received on the interface. By default, authentication is disabled.

To enable authentication, select one of the following authentication methods:
