Router config bug?

Hi,

I am trying to configure OSPF on a Cisco 1720.

When I enter the command 'router ospf 1' instead of entering router config mode, the CLI stays at global config mode and no error is being displayed. I cannot continue with OSPF.

The IOS is version 12.2(3d) and OSFP is supported on this platform.

Is this a bug in the specific version? Does anybody know about it.

thanx

Re: Router config bug?

Do you have any interfaces configured with ip addresses yet? You need IP on the router before ospf can be configured.

Yes, it is a production router and IP is configured.

Have you tried a different process ID, lets say 75 or 100? Ex:

yes.

EIGRP and RIP are working fine. BGP gives unknown protocol error.

Re: Router config bug?

enable the networks and run a debug ip ospf packets or events and see if any sort of ospf hellos are exchanged.

I guess you didn't get it correctly. I cann't enter router config mode, how am I supposed to debug ospf? The ospf process doesn't even start.

Could you post the pre-ospf config you have here?

What is the name of the image you're running (not the version, but the name)??

I believe that in the low end platforms, OSPF is only supported in the "IP Plus" image. The name should be something like c1700-sy-..., instead of c1700-y-... for the plain "IP" image.

I don't think so. As the 1700 is not that low end. I have run successfully OSFP on 1600 series routers.

But this issue is getting quite interesting. Last night I rebooted the router and guess what? I was able to configure OSPF. But then show run stopped working.

I tried to enable buffered logging with 16384 KB but the router complained about not enough memory. 4096 was OK. (This sounds strange for a 16MB router). Anyways after doing this telnet stopped responding and now I cannot login to the router, even after 2 reboots.

Note that OSPF is running as a totally stubby area so memory consumption should be minimal.

Re: Router config bug?

It does sound like you have a memory problem, to me.... What happens when you run show run? Does it just do a show memory? Can you enable ospf and only put a single loopback in it, with no "real" interfaces, to see what it does then?
