Re: Cisco 2600 IOS upgrade

I believe there are two reasons :

1) Upload the incorrect image that does not supported by 2600 or the image is crashed.

2) The config-reg. may be correct.

Try to follow below link to boot the router in ROM mode and check corresponding parameters and config. And you can follow the guide to troubeshoot the probelm. The final step is to recovery as password recovery process which is contained in the link.

Re: Cisco 2600 IOS upgrade

Thanks for reply.Problem has been resolved .It was going in initial setup mode & bypassing startup-config.I don't know why?. But same has been fixed also with IOS upgradation so that i can use cryptographic features.

Anything which will going to update my knowledge is highly accepted & Expected.
