Reboot & update your router in half the time with warm reloads!


CCIE or Null!

Reloading a router can sometimes feel right like an eternity, usually when you issue a reload you can step away get a cup of coffee sit back down and the router should be just about be ready. For quite a while now (well since before 12.4 which lets admit is a long time ago) we’ve had to ability to ‘warm’ boot Cisco routers and cut the reload time in half! The first question we probably ask, is what exactly does the router do differently to decrease the time it takes to reload? Well, When you want a router boot, what is one of the first things you see it doing?  Usually you see the router reading the flash card, grabbing the IOS and decompressing it into RAM, when you enable the warm reload feature the router skips this steps because it keeps this information in a reserved portion of memory.
