Static Route Lab
R3#show ip route, R1#show ip route, R2#show ip route
R3 can ping both R1 and R2 because they are both directly connected. How like the diagram above shows R1 can't ping R2 and vise versa.
To resolve this issue we can use static routes.
R1#ip route 10.1.128.252 255.255.255.255 10.1.130.251
R2#ip route 10.1.130.253 255.255.255.255 10.1.128.251
