Our pre-shared key is OurKey and the remote tunnel IP address is 20.20.20.20. This pre-shared key must match at the other end. When RouterA wants to establish VPN Tunnel between RouterB, this pre-shared key will be used for the authentication. We will configure pre-shared key with the ip address of the remote tunnel end.
There are other Diffie-Hellman groups available for here.Īfter these configuration steps, we will define pre-shared key for the authentication between two peers. As crypto isakmp policy group, we used group 10. We can also use rsa-sig and crack methods. We used pre-shared authentication method. We can also use DES, 3DES aes-192 and aes-256 methods.
Now, let’s explain that what we have used here. RouterA(config-isakmp)# authentication pre-share
