cisco ISR

Hello everybody,  I have a question. How to update IOS ISR on both routers if they are in HSRP? Act-Stb. On Act, I downloaded iOS without an extension, but on Stb it doesn’t let it. What to do?

Can you post the output when you try this?

We want to see the command syntax used and the error message(s) that appears.

I do not know the update procedure, how to download iOS on the ISR then what is Stb? I only got it on Active. Because only ssh on mgmt works on Stb

Copy the IOS to the Active.
Copy the IOS to the Standby.
Change the boot variable string of the Active unit.
Change the boot variable string of the Standby unit.
Reboot.
