What is the model and company ?
Many default config of routeur block ICMP-ping. So make sure you have enable this fonction.
Just in case, be sure to desactivate DHCP on 1 of them !!

Are there any access lists perhaps blocking pings?

Can you post the config from the routers?

they are both 2600 routers.

I have a cross over between them.
as craigbeck ask you,

can you post the config of both router

As jrobillard and craigbeck said please post up the config.

While your doing that check and make sure the cable is working ok. Sometimes you will see a link light beside the FastEthernet ports. Can you please check and see if you have L2 connectivity by checking the light beside the cable.

please post

show ip arp

to see if the other router has responded with it's mac address.

also try

show cdp neighbor

To answer your question though, no, you don't need any routers. If there is a link between the devices, it is directly connected and a route is automatically inserted into your routing table.

Post your configs!
