Cisco 2811 as a Backup Router - Need Security Package?
Posted on 2010-08-30
I currently have a Cisco 2811, it's just a basic Cisco 2811, no special stuff just "Cisco 2800 IOS IP BASE" as we bought it when we had a Cisco Pix 506E firewall installed (still do) everything works fine. Except for last week when it seemed that the Cisco 2811 lost it's config. (we restored it, all is OK)
It took us a lot of time to figure out what was going on and now we'd like to have backup hardware to swap out instead of wasting hours finding the issue. Compounding the difficulty we weren't sure if the problem was the firewall...
We'd like to have a single point of failure we could swap out, so we are looking to get rid of the 506E firewall.
We are going to be purchasing a backup Cisco 2811 router shortly and wanted to know if I should get one with the "Cisco 2800 IOS ADVANCED SECURITY"? I am not sure if the "Cisco 2800 IOS ADVANCED SECURITY" would take over the Cisco Pix 506E firewall duties allowing us to get rid of that hardware?
If it does, I will want to replace my current Cisco with the new one with the added firewall software.
And also, do I need to buy an add on for my other original Cisco 2811 to make it identical?
Is the "Cisco 2800 IOS ADVANCED SECURITY" just part of an image that I can backup and copy to the other router in case of failure? (I will only be running one at any one time, so I am not sure of licensing on this??)
I don't understand the softare or "add ons" side of things here, is it just software embedded?
I guess I have two questions:
1. Will the "Cisco 2800 IOS ADVANCED SECURITY" take over for the 506E Firewall if programed properly?
2. Do I need to buy an add on for my original or can I just copy the routers firmware or image over to the original?
(note: they will never run concurrently as one will always be in a box)
