Is there a document that explains the difference between the feature sets available for IOS software? I would like to know if I'm choosing the right one. Up to this point, I've downloaded new IOS based upon the feature set already on the router. But would IP PLUS be better for my branch offices than just IP? Or do I even need ENTERPRISE/FW/IDS PLUS IPSEC 56 on my core router? I'm sure it has something to do with providing the proper command set to configure the router how you want to, but I have been able to determine what those differences are to make an informed decision to change the feature set currently running.
Thanks,
