To remove an IPsec encryption policy from an interface, enter the no ipv6 ospf encryption ipsec spi number command. To remove null encryption on an interface to allow the interface to inherit the encryption policy configured for the OSPFv3 area, enter the no ipv6 ospf encryption null command. To display the configuration of IPsec encryption policies on the router, enter the show crypto ipsec policy command. To display the security associations set up for OSPFv3 interfaces in encryption policies, enter the show crypto ipsec sa ipv6 command. Configuring IPsec Authentication for an OSPFv3 Area Prerequisite: Before you enable IPsec authentication on an OSPFv3 area, you must first enable OSPFv3 globally on the router (refer to Configuration Task List for OSPFv3 (OSPF for IPv6)). To configure IPsec authentication for an OSPFv3 area, enter the following command in global configuration mode: Command Syntax Command Mode area-id authentication ipsec spi number {MD5 | SHA1} [ key-encryption-type] key CONF-IPV6ROUTER-OSPF Usage Enable IPsec authentication for OSPFv3 packets in an area, where: area area-id specifies the area for which OSPFv3 traffic is to be authenticated. For area-id, you can enter a number or an IPv6 prefix. spi number is the Security Policy index (SPI) value. Range: 256 to 4294967295. MD5 | SHA1 specifies the authentication type: message digest 5 (MD5) or Secure Hash Algorithm 1 (SHA-1). key-encryption-type (optional) specifies if the key is encrypted. Valid values: 0 (key is not encrypted) or 7 (key is encrypted). key specifies the text string used in authentication. All neighboring OSPFv3 routers must share the same key to exchange information. 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). An SPI value must be unique to one IPsec security policy (authentication or encryption) on the router. You must configure the same authentication policy (same SPI and key) on each interface in an OPSFv3 link. 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 ipsec spi number command. Open Shortest Path First (OSPFv2 and OSPFv3) | 697
