I am having a problem with my network. I have a router (R1) connected to another router (R2) R1 is connected to a switch. R1 switch has two PC's connected to it. the PC IP's are 128.107.35.10 and 192.31.7.10. The default gateway is 198.133.220.1. when i ping from the R1 PC's i get request timed out. when i ping from R2 PC's i get destination host unreachable. I have OSPF and RIP v2 on both routers.
Does anyone know why this is happening?
