I have a very interesting question that I believe not many would not the answer to.
Nothing like a good challenge on a Monday morning....
Anyway, I would like to know if it is possible to replace a CISCO 3825 router with a CISCO 3750-E switch?
Generally the answer is yes, however I have I need to ensure that the switch has the IPSEC(AES) Feature available.
The router needs to have the Security bundle shipped with it to have this feature.
I have a attached a sample configuration that is used on the router. If you're able to say if the same is available on the 3750 or not, I would greatly appreciate it.
I have looked at numerous websites and CISCO documentation, but so far not found anything concrete.
I thought that maybe one of the experts may be able to provide an answer...
You haven't attached a config file but in answer to your question if you are referring to IPSEC VPN functionality a 3750-E switch will not support this.
The only catalyst i know that will support this is the 6500 although even there you need additional hardware.
