First off, I apologize if this is in the wrong section. I didn't see a hardware or IOS section, if there is one (or if there is a section which is more appropriate) I'm sorry I didn't know.
I have a Cisco 1921 ISR Router with Security License running software version 15.0. I want to upgrade the router to 15.1. But I don't want to lose the security license that came with the router. When I look at the IOS downloads page on Cisco, all I see is universal images for all versions of 15.1.
My question is - where is the security license stored? In the IOS or programmed in somewhere else of the router? If I upgrade my router to one of the newer 15.1 universal images, will I lose my security license? Thanks in advance.
Thanks for posting back and answering your own question. This may be helpful to other readers who may have similar uncertainty. And having an answer from someone who can say that they have actually done the upgrade themselves makes the answer more valuable.
And there is not a section of the forum for hardware or for IOS specifically. So this forum was a quite appropriate place to post your question.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
