Configuration

Router1: ConfigurationRouter>enable
Router#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#hostname Router-1

Configuring Static Route on all 3 routers: 

Router-1(config)#ip route 11.0.0.0 255.0.0.0 10.0.0.3
Router-1(config)#ip route 192.168.2.0 255.255.255.0 10.0.0.3
Router-1(config)#exit

Router-2(config)#ip route 192.168.1.0 255.255.255.0 10.0.0.2
Router-2(config)#ip route 192.168.2.0 255.255.255.0 11.0.0.3
Router-2(config)#exit

Router-3(config)#ip route 10.0.0.0 255.0.0.0 11.0.0.2
Router-3(config)#ip route 192.168.1.0 255.255.255.0 11.0.0.2
Router-3(config)#exit

Verification: 

Check the routing table on all the three routers
