I am planning to upgrade BootLoader image of 7206VXR router due to booting issue. The router is not booting .But if I go to rommon and give boot it will boot.

So I am upgarding my Boot Loader image. Now the Bootloader image and IOS image are exactly same.

Can I upgarde the Bootloader image to latest version without upgarding IOS. ?

Should both have to be same ?

Will it cause any issue if both are different.?

Please provide link to good documentation on this

Please advice

Thank you,

If its not booting I would check both the config register and your boot statements, I would bet it is one of those . The bootloader would not have anything to do with it not booting I don't believe . I always try to keep the IOS and bootloader the same even though they don't have to be .

The config register is 0x2102 and the boot system is also configured correctly.
