authentication-
algorithm
Specifies the authentication algorithm to use for encryption.
Valid values are MD5 or SHA1.
key-encryption-
type
(OPTIONAL) Specifies if the authentication key is encrypted.
Valid values: 0 (key is not encrypted) or 7 (key is encrypted).
key
Text string used in authentication.
For MD5 authentication, the key must be 32 hex digits (non-encrypted) or 64 hex digits
(encrypted).
For SHA-1 authentication, the key must be 40 hex digits (non-encrypted) or 80 hex digits
(encrypted).
null
Causes an encryption policy configured for the area to not be inherited on the interface.
Defaults Not configured.
Command Modes ROUTER OSPFv3

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.
