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.
