If all steps were followed correctly, tunnel interface should be active. But as with any other configuration, it is always wise to test the setup in order to make sure that it works properly. In order to test the GRE Tunnel connection, login to RUT WebUI and go to '''Services → CLI'''. Login with user name: '''root''' and the router's admin password. From there you should then be able to '''ping''' the opposite instance's virtual IP address. To use a ping command, type '''ping <Cisco_ip_address>''' and press the "Enter" key on your keyboard. You can also check it form Cisco routers side, connect to router with PuTTy or equivalent program and use same ping command '''ping <RUT_ip_address>'''.
