Cisco 2600 router 2 internal networks

I have a new cisco 2600 router. It is used to segment beetween 2 internal lan nets - 10.10.0.0 & 10.80.0.0.

I have the interfaces set with correcct IP. THey are both up.

From the router I can ping all stations on either network fine.

I can not ping from a workstation on the 10.10. network to the 10.80 network. It is not crossing the router. IP and IPX routing is set on both interfaces.

I thought that the routing was automatic.

What could the problem be?????

Thank you

Try the following sequence while in enable mode:

config t

ip routing

exit

write mem

You may check your routing table by issuing the command:

sho ip route

The classful router is looking at the 10.x.x.x network as a class A or 255.0.0.0 masked network. It will naturally drop any packets it doesn’t think it owns. Turn off this “classful” thinking by typing ‘ip classless’ in global config mode.

Try to use extended ping from the router and ping a device on network 10.10 using the router interface IP address on the 10.80 network. If you don't get a reply, it could be wrong default gateway on all the devices on your LAN.
