Since it's a packet tracer file, can you provide the exercise file so I can take a look? It can be a number of things, from wrong subnetting/subnet masks, to bad config...

hi I've uploaded it in the edit, thanks for replying.

Ok the issue is that all the routers do not know the way (path) to all the networks you need.

I'm not sure how far you are into your studies, but like /u/dave_881 said, when using RIP, you need to use version 2 on all the routers because you are using class A networks and RIP V1 does not use the mask for a class A. In command line you need to enter (on each router):

router rip
version 2

However, if you are using static routes, then you are telling the router what paths to use and those paths have priority over protocol learned routes. So, you need to change your static routes to (an example):

In 1st:

ip route

In Main:

ip route
ip route

In 2nd:

ip route

I'm not sure if this is going to overwhelm you or not, but shout out if you need further assistance!

Thanks, it's all clicked now! I was under the assumption it was already using RIP v2 and had the knowledge that RIP one didn't support classless addressing. I'm not studying CCNA, I'm an apprentice and focus more on the cyber element, I just have coursework to build a network in packet tracer.

thanks /u/dave_881 and /u/Cristek

once you both mentioned about RIP not being version two it all fell into place, I can now resume after weeks of frustration.

Remember that there's 2 ways of doing this, either with a routing protocol (RIP EIGRP OSPF); or; with static routes. Only one method is needed. However if both are configured, static routes, by default always take priority over Routing Protocols!

How does one go about implementing EIGRP and OSPF in Packet tracer. I understand the benefits of these protocols in terms of redundancy so I would prefer to use them /u/Cristek however there is only RIP and static routing options within the router. I can imagine the CLI but where would this display like static routing and RIP would via the GUI?

RIP version 1 doesn't understand classless routing.

Set RIP version to 2, under the router rip configuration section.

In rip v2 you need no auto summary.
