Hello,
2 things. You need to turn off
auto summarization
under the router rip process (see below) and your G0/2 interfaces connecting to the switch to form neighbors is all the same IP address. They cannot be the same IP because then the router thinks the update is coming from itself and will discard it.
R0-G0/2: ip address 10.0.0.1 255.255.255.0
R1-G0/2: ip address 10.0.0.2 255.255.255.0
R2-G0/2: ip address 10.0.0.3 255.255.255.0
Also make sure they are in the same subnet with appropriate mask. Since you don't have the 10.0.0.0 network anywhere else I would just use
255.255.255.0
Under the Router RIP configuration turn off the
auto summarization
conf t
router rip
no auto-summary
Hope that helps

Thanks David! Your answer solved my problem! btw, my mask
255.255.255.248
doesnt work but
255.255.255.0
works?

Your mask of
255.255.255.248
would have worked since it would allow for 6 hosts and you only needed 3 (1 for each router). But you still needed to make the IPs unique. I just used the /24 of
255.255.255.0
as an example.
