Bootloop on Router 2611XM

Hello guys, I'm trying to start one cisco router, but the boot is always in loop, cause of some error.

I cant stop the boot in order to clear the config files, or even acess the cli.

The output is below:

Hi Diogo,

This does not look good. Segmentation violation are caused either by grave software errors or by hardware fault, most commonly, RAM issues.

I would suggest using a different IOS image with a lower feature set that consumes less memory. If that IOS boots up, there is a good chance that just the IOS image you originally had at the router is corrupt, tried to use too much memory, or has some issues. If the problem persists, you may still try pulling out all WICs and NM modules out of the router, leaving just the barebone router to boot up. If nothing helps, I am afraid the only option left is to try replacing the DRAM modules.

Best regards,

Peter

Well, I tried it.

I managed to enter in rommon and using XModem uploaded the ios:

c2600-ik9o3s3-mz.123-22.bin

But the problem persists :X

New update:I loaded a new IOS:

c2600-i-mz.123-22.bin

and It worked

The issue now is, will the funcionalities work with this ios, like vpn and so?

If not, what IOS you advice me to put?

Thanks in advance.

Hello Diogo,

You have put an IOS with the basic IP feature set. I am almost sure that VPN will not work with this IOS.

Can you post the output of show version command here? In order to help you, I need to know the amount of your DRAM and FLASH.

Best regards,

Peter
