The values are 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).
Defaults Not configured.

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.
