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 pre-shared keys, select either a manual key or an automatically generated key. Specify this key in the IKEv1 or IKEv2 options. When you deploy your configuration, the key is configured on all devices in the topology.
