Reference Guide

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 (256 to 4294967295).
● md5 — Enable MD5 authentication.
● sha1 — Enable SHA-1 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 SHA-1 authentication, the non-encrypted key must be 40 hex digits. An encrypted key
is not supported.
Example
OS10(config-router-ospfv3-100)# area 1 authentication ipsec spi 400 md5

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 (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 algorithm to use (MD5 or SHA1).
● key — Enter the text string used in the authentication algorithm.
Default OSPFv3 area encryption is not configured.
Command Mode ROUTER-OSPFv3
Usage
Information
● Before you enable IPsec encryption for an OSPFv3 area, you must enable OSPFv3 globally on each
router.
● 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
(area ospf authentication ipsec). To configure encryption, you must first delete the
authentication policy.
● All OSPFv3 routers in the area must share the same encryption 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.
● 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 SHA-1 authentication, the non-encrypted key must be 40 hex digits. An encrypted key
is not supported.
