Administrator Guide
If you have enabled IPsec authentication in an OSPFv3 area with the area authentication command, you
cannot use the area encryption command in the area at the same time.
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.
