Usage
Information
Before you enable IPsec authentication on an OSPFv3 area, you must first enable OSPFv3 globally on the
router. Configure the same authentication policy (same SPI and key) on each interface in an OSPFv3 link.
An SPI number must be unique to one IPsec security policy (authentication or encryption) on the router.
If you have enabled IPsec encryption in an OSPFv3 area with the area encryption command, you
cannot use the area authentication command in the area at the same time.
The configuration of IPsec authentication on an interface-level takes precedence over an area-level
configuration. If you remove an interface configuration, an area authentication policy that has been
configured is applied to the interface.
To remove an IPsec authentication policy from an OSPFv3 area, enter the no area area-id
authentication spi number command.
