RIP Overview

This chapter describes how to configure the Routing Information Protocol (RIP) on the SmartSwitch Router. RIP is a distance-vector routing protocol for use in small networks. RIP is described in RFC 1723. A router running RIP broadcasts updates at set intervals. Each update contains paired values where each pair consists of an IP network address and an integer distance to that network. RIP uses a hop count metric to measure the distance to a destination.

The SmartSwitch Router provides support for RIP Version 1 and 2. The SSR implements plain text and MD5 authentication methods for RIP Version 2.

The protocol independent features that apply to RIP are described in Chapter 6, “IP Routing Configuration Guide” on page 85.

Configuring RIP

By default, RIP is disabled on the SSR and on each of the attached interfaces. To configure RIP on the SSR, follow these steps:

1.Start the RIP process by entering the rip start command.

2.Use the rip add interface command to inform RIP about the attached interfaces.
