○ key - Enter the text string used in the authentication type. All OSPFv3 routers in the area share the key to exchange information. Only a non-encrypted key is supported. For MD5 authentication, the non-encrypted key must be 32 plain hex digits. For SHA1 authentication, the non-encrypted key must be 40 hex digits. An encrypted key is not supported. To delete an IPsec area authentication policy, use the no area area-id authentication ipsec spi number command.

When you configure encryption at the area level, both IPsec encryption and authentication are enabled. You cannot configure encryption if you have already configured an IPsec area authentication using the area ospf authentication ipsec command. To configure encryption, you must first delete the authentication policy. • Enable IPsec encryption for OSPFv3 packets in an area in Router-OSPFv3 mode. area area-id encryption ipsec spi number esp encryption-type key authentication-type key ○ area area-id - Enter an area ID as a number or IPv6 prefix. ○ ipsec spi number - Enter a unique security policy index (SPI) value, from 256 to 4294967295. ○ esp encryption-type - Enter the encryption algorithm used with ESP (3DES, DES, AES-CBC, or NULL). For AES-CBC, only the AES-128 and AES-192 ciphers are supported. ○ key - Enter the text string used in the encryption algorithm. All neighboring OSPFv3 routers must share the key to decrypt information. Only a non-encrypted key is supported. Required lengths of the non-encrypted key are: 3DES - 48 hex digits; DES - 16 hex digits; AES-CBC - 32 hex digits for AES-128 and 48 hex digits for AES-192. ○ authentication-type - Enter the encryption authentication MD5 or SHA1 algorithm to use. ○ key - Enter the text string used in the authentication algorithm. All neighboring OSPFv3 routers must share the key to exchange information. Only a non-encrypted key is supported. For MD5 authentication, the non-encrypted key must be 32 plain hex digits. For SHA1 authentication, the non-encrypted key must be 40 hex digits. An encrypted key is not supported.
