Auto-Cost - Dell C9000 Series Reference Manual

Usage Information Before you enable IPsec encryption on an OSPFv3 interface, first enable OSPFv3
globally on the router. Configure the same encryption policy (same SPI and keys) on
each interface in an OSPFv3 link.
An SPI value must be unique to one IPsec security policy (authentication or encryption)
on the router.
When you configure encryption for an OSPFv3 area with the area encryption
command, you enable both IPsec encryption and authentication. However, when you
enable authentication on an area with the area authentication command, you do
not enable encryption at the same time.
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.
