Need help with gateway-to gateway vpn config

[sasma]

Hello everybody, hope you all are doing well!

For my graduation project, i was provided two cisco 1841 routers and two switches, i have configures two separate LANs with those routers, my goal was to create a site to site VPN tunnel between the gateway of those LANs and since these are connected to my ISP, i thought it would be easy, however my routers cannot recognize the "crypto" command.

Is there any other way i can connect those LANs together to create a WAN?

to create IPSec tunnel you need sec license in router. if you dont have that, you can easily use normal routing to connect two sites. to understand better, you need to provide diagram of connectivity.

Hello kasun, i just uploaded a network diagram, if you would direct me on how to connect my two LANs that would be helpful

Hi,
What routers do you use for your setup?

Most probably you're not running a k9 ios image.
