How to Configure Routing Information Protocol (RIP)

Overview

This document describes how to configure Routing Information Protocol (RIP) on a Palo Alto Networks device.

Example scenario:

Steps

1. Go to Network > Virtual Router and check default.
   
2. Select RIP and add the interface to enable the protocol.
   
3. Select the interface and check Enable and Advertise, as shown below.
   
4. Enable the RIP protocol, as shown below.
   
5. Follow the same steps for other Palo Alto Networks devices and check the neighbor state.

>show routing protocol rip peer
  ==========
  virtual router:               default
  peer address:                 13.0.0.1
  last update:                  Wed Nov  5 01:52:54 2014
  RIP version:                  2
  invalid packets:              0
  invalid routes:               0

  ==========
virtual router:                default
reject default route:          yes
redist default route:          block
interval seconds:              1
update intervals:              30
expire intervals:              180
delete intervals:              120
interface:                     13.0.0.2

6. Check routing table and RIP database table, as shown below.
