connect two routers on different ip subnets

[Bob Greer]

Hi there,

Thanks for reading.  I've got a dumb question.  I can't route between two routers.  I'm working in Packet Tracer with a two device network. The infs facing each other are configured:

R1

int g0/0

ip add 1.1.1.1 /24

no shut

ip route 2.2.2.0 255.255.255.0 g0/0

R2

int g0/0

ip add 2.2.2.2 /24

no shut

ip route 1.1.1.0 255.255.255.0 g0/0

The routers see each other in show cdp nei det.  The infs are no-shut.  I know it's something ridiculously simple.

Thanks again for reading!

Bob

Bob,

CDP is layer 2, that is why the routers see each other. For layer 3 connectivity, the direct link needs to be on the same subnet.
