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
