Users Guide

The configuration of IPsec encryption on an interface-level takes precedence over an area-level
configuration. If you remove an interface configuration, an area encryption policy that has been
configured is applied to the interface.
To remove an IPsec encryption policy from an interface, enter the no area area-id encryption spi number
command.
