Defining User Reauthentication Protocol Values

The extended-authentication command specifies the extended user authentication
protocol for use during the extended user authentication protocol exchange.
The re-authenticate keyword enables the reauthentication option (a subsequent
authentication procedure). When this option is enabled, rekeying of IKE SAs uses
the initial authentication protocol to reauthenticate the user. When this option is
disabled, authentication is only performed at the first IKE SA establishment.
Subsequent IKE SAs rekey operations inherit the initial authentication and do not
reauthenticate users.
NOTE: For maximum security, enable reauthentication.
The skip-peer-config keyword disables the router from configuring peer IP
characteristics.

Use to specify the IPSec lifetime parameters used on IPSec SA lifetime

Use the no version to return the lifetime to its default value, 28800 seconds (8
hours) and no traffic volume limit.
See lifetime.

The re-authenticate keyword enables the reauthentication option (a subsequent
authentication procedure).

characteristics.
Example
