Hi Everyone,
I see hew Tunnel interface on Router.
Router is Running OSPF.
It has no crypto statemets.
tunnel configuration
interface Tunnel1
ip address 10.4.x.x x.x.x.x
delay 7
tunnel source Loopback1
tunnel destination 10.4.x.x
My question is when we use Tunnel interface without any crypto statemets?
Thanks

This Tunnel is a plain GRE-Tunnel. These are typically used without crypto when:
1) The traffic is not sent through an untrusted network and a cryptographic protection is not needed.
2) The GRE-traffic gets encrypted on a separate device if the GRE-Endpoint is not capable of doing the needed cryptographic protection.

Hi Karsten,
Thanks for reply.
So you mean this is possible where we only need GRE tunnel on device and this device can communicate to other
end of tunnel and other device can do the IPSEC encryption right if needed?
Thanks
