Hi Guys this is a requirement that my teacher assigme, I can´t do it... is posible?
-L-1 and L-2 they must communicate via the ethernet shared by "S-AR to Central as primary path, while the serial connection between R-1 and R-2 will be as a backup path to be inserted if the ethernet falls.

ip route 0.0.0.0 0.0.0.0 s0/0/0 5
But I can´t comunicate because the packet can go out but it can´t come back. help me!
