Packet Tracer Class Lab - Understanding RIP

This Packet Tracer lab has been provided to help you gain a better understanding of how to configure and troubleshoot RIP version 2 in this lab we will configure a basic lab topology, enable RIPv2 on the routers and configure them to advertise their networks.

Learning Objectives:

Review basic router and switch configuration.
Enable RIPv2 on a router.
Advertise networks using RIPv2.
Observe and inspect RIPv2 Packets

The Routing Information Protocol (RIP) is one of the oldest distance-vector routing protocols, which uses the hop count as a routing metric. RIP avoids routing loops by employing a limit on the number of hops permitted in a path from the source to a destination. The maximum number of hops permitted for RIP is 15. A hop count of 16 is considered an infinite distance, in other words the route is considered unreachable. Despite this limitation, RIP works great for basic route communications between devices.

Here are some important RIP facts:

Cisco routers don't enable RIPv2 by default. To use RIPv2, you must use the ver 2 command in RIP Router Configuration Mode.
RIP uses hop count as it’s metric.

How RIP works

With RIP, a router sends its full routing table to all other connected routers every 30 seconds. Triggered updates can also occur if a router goes down before the 30-second timer has expired.

RIP performs "routing by rumor" and is more prone to loops than other routing protocols. That's because a RIP router sends its entire routing table to every other router. All other routers do the same, and because there's no real neighbor relationship or calculation of routes, the routers have little firsthand knowledge of available networks.

LAB:

Using the same starter

from the "Static Route" lab, we will now configure the network using RIP. This means that the routers will learn about neighboring routers and network through RIP Broadcasts

Configuring RIP involves
- Enabling it on the router
- and, declaring which of the directly connected networks should be advertised
Here is the configuration for R2 in our example:
- From "config" mode type:
  - router rip
- This will now put you in "router config mode"
- Then specify the version with
  - version 2
- And then specify the networks directly connected to Router 2
  - network 192.168.30.0
  - network 10.10.20.0
- Thats it!
Repeat Step 2 for R1 and R3
- Make sure to update the network statements to specify the correct networks for those routers!
If it is working, all PC's should now be able to ping one another
Go to R2, exit "config" mode, and type "show ip route". You should see all of the the networks in the table. Post Screenshot
Repeat Step 4 for R1 and R3. Post Screenshots

Inspect RIP Activity

In Packet Tracer - switch to "Simulation Mode" (Stopwatch icon in Lower Left)
Under Event List Filters - Visible Event - Click Show All/None
Then click Edit Filters - and Select RIP
Click the "Capture/Forward" button in the lower center of the screen repeatedly. You should see RIP packets traversing the network.
In the upper right Event List - find a packet for RIPv2 from R1 to R2
Click the colored "info" box to display the packet details.
Click the Inbound PDU Details tab
Scroll down to RIP v2 section
