PC's wont talk to each other for some reason

Im beginning my CCNA training again after taking time off from Cisco to focus on other things. I have a very basic packet tracer set up which involves two routers talking to each other which two switches follow along with a PC at the end. I've set up the router RIP route as following:

 

Router rip

Network 10.0.0.0

Network 192.168.0.0

Network 172.16.0.0

 

I am able to ping between the routers with no issues. the problem is when I try to ping from PC2 to PC0 or PC1 it wont work. Now if I swap the cable to Serial DCE connection it works just fine. Is there a reason for this? This is my set up:

 

route.PNGRouter 1's config:

Solved my own problem.

 

For some reason adding a router rip 192.168.0.0 doesnt work. when i spit the actual routes out ex 192.168.2.0 192.168.1.0 etc then it sees that. not sure why

This is because you are using the RIP V1 which is Classful routing protocol. If you want to use the classless subnet as you mention 192.168.0.0 then use the RIPV2 and no auto summary. 

 

And for routing issue serial interface. Please share the actual lab file, because in your running configuration there is much confusion about default route and RIP and serial interface configuration.

I solved my own problem

 

router rip

192.168.0.0

wont work.

 

it wants specific routes  ex 192.168.1.0 192.168.2.0 etc. Not sure why

 

Hi

I recommend to use RIP version 2 because the version 1 will not accept classless updates, so the configuration on your router should be:

 

conf t

router rip

version 2
