When you configure encryption on an interface, both IPsec encryption and authentication are enabled. You cannot configure encryption if you have already configured an interface for IPsec authentication (ipv6 ospf authentication ipsec). To configure encryption, you must first delete the authentication policy. • Enable IPsec encryption for OSPFv3 packets in Interface mode. ipv6 ospf encryption ipsec spi number esp encryption-type key authentication-type key • ipsec spi number - Enter a unique security policy index (SPI) value (256 to 4294967295). • esp encryption-type key - Enter the encryption algorithm used with ESP (3DES, DES, AES-CBC, or NULL). For AESCBC, 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 key - Enter the encryption authentication algorithm to use (MD5 or SHA1). • 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 SHA-1 authentication, the non-encrypted key must be 40 hex digits. An encrypted key is not supported. To delete an IPsec encryption policy, use the no ipv6 ospf encryption ipsec spi number or no ipv6 ospf encryption null command.
