Pre-shared keys

A pre-shared key is a secret key that

  • enables you to share authentication credentials between two peers

  • is used by IKE in the authentication phase, and

  • must be configured identically on each peer or the IKE SA cannot be established.

Key configuration options

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.
