Me, I prefer real kit mostly becasue all the time I spend trying to make GNS3 behave is better spent on labs than trying to make the thin that hosts the lab work. I'm sure someone will chime in and suggest Packet Tracer (which is fine) or GNS3 which is fine IF you can get hold of the IOS that GNS3 will run. I regularly swap mine around when I get tasks that require a specifc feature.
And remember you can always copy the IOS between routers. It's not until you get to the heavier NP specialisations that you might need a specific IOS for a specific festure. They will all do what you need them to for the CCNA. IOS type on the 1841 is largely irrelevant. Three is a minimum and 5 is optimal because it allows for some advanced scenarios. There will be a Cisco datasheet that lists the full feature-set of the IOS.Īnd you'll need more than one router. If you want to know the specific capabilities of the IOS just Google it. I've got about three different IOS for the 1841 including the one you mention and they all do way more than is needed for the CCNA. Can you tell me please, is it good system IOS ( ADVSECURITYK9-M ) for home lab testing and preparing for CCNA 200-301 exam? All routing protocols will work ?
