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