Pre-shared Keys
Pre-shared key enables you to share a secret key between two peers. IKE uses the key in the authentication phase. You must configure the same shared key on each peer, or the IKE SA cannot be established.
To configure the pre-shared keys, choose whether you want to use a manual or automatically generated key, and then specify the key in the IKEv1/IKEv2 options. Then, when you deploy your configuration, the key is configured on all devices in the topology.
