OSPFv3 Commands
area authentication
Configures authentication for an OSPFv3 area.
Syntax
area area-id authentication ipsec spi number {MD5 | SHA1} key
Parameters
● 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.
● md5 — Enable MD5 authentication.
● sha1 — Enable SHA1 authentication.
● key — Enter the text string used in the authentication type.
Default OSPFv3 area authentication is not configured.
Command Mode ROUTER-OSPFv3
Usage
Information
● Before you enable IPsec authentication for an OSPFv3 area, you must enable OSPFv3 globally on each
router.
● All OSPFv3 routers in the area must share the same authentication 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.
Example

area encryption
Configures encryption for an OSPFv3 area.
Syntax
area area-id encryption ipsec spi number esp encryption-type key
authentication-type key
Parameters
● area area-id — Enter an area ID as a number or IPv6 prefix.
● ipsec spi number — Enter a unique security policy index number, 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.
● authentication-type — Enter the encryption authentication MD5 or SHA1 algorithm to use.
● key — Enter the text string used in the authentication algorithm.
Default OSPFv3 area encryption is not configured.
