Hello,

According to this output is more than clear that you don't have a k9 license applied to this router, this license will allow security features on your IOS, on this case you will need to get a k9 license with an activation key and then you will be able to have the crypto commands available on your device. Once you have this we can work on the site to site configuration.

Don't forget to rate!
