Usage Information
Before you enable IPsec encryption on an OSPFv3 interface, rst enable OSPFv3 globally on the router.
Congure 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 congure 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 conguration of IPsec encryption on an interface-level takes precedence over an area-level
conguration. If you remove an interface conguration, an area encryption policy that has been congured is
applied to the interface.
To remove an IPsec encryption policy from an interface, enter the no area area-id encryption spi number
command.
