RIP protocol not working

[Marry Poppins]

Hello!

I am quite new to networking and I was trying to create a network using the RIP protocol as well (because I have two routers). However, I kept trying to add the protocol but the packets are still not sent properly. I also noticed that when i was adding 9.9.9.0 network to rip, it was transforming it 9.0.0.0 and I don't know why this is happening. 

The packets are sent between the routers, but not between the networks. I attached the configuration file, maybe someone is kind enough to help me out a little. Thank you so much!

Hi @Marry Poppins ,

You need to configure "router rip" on both Router0 and Router2. 9.9.9.9 is recognized as 9.0.0.0, because rip is a classful routing protocol and the natural network mask for 9.9.9.9 in that context is 255.0.0.0.

Router0

router  rip 

network 9.0.0.0

network 10.0.0.0

Router2

router rip

network 8.0.0.0

network 9.0.0.0

Hello

Try the following then rip should advertise the correct route and mask in the routing table but it will still show up as classful in the routing stanza

router rip
no auto-summary
version 2

If you're quite new to networking, you might be unaware of classful (as noted by Harold and Paul) vs. classless addressing.  Classful addressing has many "quirks" to it, one of which, you've found in routing protocols that use it, such as RIP.  RIPv2, although it "supports" classless, has its own "quirks", one of which mentioned by Paul.

If you search the Internet, you'll find much information about classful and classless addressing.  Unfortunately, be prepared to allocate some time to study it because at first, often, it's a bit confusing.
