hi Kavithas,

For ISRG2 - the Universal IOS image is loaded by Cisco manufacturing on all shipped routers. IOS Universal Image contains all IOS features. Feature sets in the universal image are unlocked using licensing keys i.e. the level of IOS functionality available is determined by the license applied to the device. A new license only needs to be applied to upgrade IOS functionality on the router .Moving from one IOS universal image version to another does not require a new licensing key. Reboot of router is also licensing transparent.

Each licensing Key is unique to a particular device and is obtained from Cisco by providing the product ID and serial number of the router and a Product Activation Key (PAK), which is provided by Cisco at time of Software purchase. Therefore is not directly dependent on the software used.

Hope this helps!

Regards,

Karthik

I need to know one more thing,

The method of upgrading IOS is only be done by

Deteleing the older IOS and installing the New IOS?

Or should it be done in any other way?

Hi

No need to delete the IOS. When you upload the new IOS image and it asks for reboot, the router reboots with new IOS.

You dont have to delete anything.

That is not correct. By default router boots the first valid image foudn, that may or may be not, the newly loaded one.

So when one wants to keeps multiple images on router, the boot command must be used.

Otherwise, it is enough to delete the old image.
