Configuring an IPsec policy that uses IKE by referencing an IPsec policy template
The parameters configurable for an IPsec policy template are the same as those you configure when
directly configuring an IPsec policy that uses IKE. The difference is that more parameters are optional.
•
Required configuration: The IPsec proposals and IKE peer.
•
Optional configuration: The PFS feature and SA lifetime.
To configure an IPsec policy that uses IKE by referencing an IPsec policy template:
Step Command

By default, an IPsec policy references
no IPsec proposal.
