I have a configuration where two Cisco routers are in different subnets. The first one is in 192.168.0.0/24 and the second one is in 192.168.1.0/24. The routers are connected via serial by the 192.168.2.0/30.
My problem is that I cannot ping computers from 192.168.0.0/24 to 192.168.1.0/24. I set a static route to 192.168.2.0/30 in order to make all traffic from 192.168.1.0/24 go to serial's router.
