Cisco 2600 - Can't ping routers own IP address

I have a new Cisco 2600
I've configured FastEthernet0/0 with correct IP address and mask.
I can't even ping the address I've assigned it, forget about pinging anything outside.
What may I be doing wrong?
Thanks

what about the interface is it shutdown or not
interface fastethernet 0/0
ip address 10.0.0.1 255.255.255.0
no shutdown
exit

Cheers

Protocol is up and line is up
Thanks, I was aware of that,
no go. I also for the heck of it reloaded the router.

How long was the router up when you issued the "show interface" command above?

6 lost carriers, 3 interface resets.

If these stats were accumulated over a couple minutes, that would be a good starting point.

It has not been up too long at all. I rebooted it within the past hour or so.
The Interface i did a shut and no shut even more recently then that.

I would start with a different cable and see what happens.

Commented:
OK I'll try, but shouldn't I be able to ping from the router the IP I assigned to the router? Even if the cable is bad?

Commented:
Thanks for all the help but I got from the T1 company bad IP information. I got the correct info, and all is working as advertised.

That's a neat trick. Ethernet to T-1.

Is there something wrong with that?

Only that it's impossible to connect an ethernet port to a T-1 line.

cisco routers have by default an ACL permiting only 10.10.10.xx networks assigned on the ethrnet interface. It usually has number 23.Check your config to see if this acl is applied to your incoming port. You can see that form show run command , check if acce

Cisco routers have NO access-lists by default.

Want to bet donjohnston????? Check a new one!!

Three days ago I set up a new 2821 and it had that access list exactly as I describe to you!!

Commented:
Also they have a default ip address of 10.10.10.1 on their network interface

I think you must be referring to Switched Virtual Interfaces.

Not really. I am talking about the default conf of a new router. It has a DHCP enabled with a lease up to 10.10.10.7 and an ACL permitting hosts only from this range. As I told I had this problem a few days ago. I've log from console , change the ip and no shut the network interface and also gave the comands login local and password on the vty interfaces. When I tried to connect I had no reply as my network was on a 192.168.1.xx subnet. I've checked the configuration and I 've seen the acl we are talking about.

When I turned off the acl everything worked fine. Please check it when you have a new router.
