• 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. 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 using the area ospf authentication ipsec command. 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 nonencrypted 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 nonencrypted 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 OS10(config-router-ospfv3-100)# area 1 encryption ipsec spi 401 esp des 1234567812345678 md5 12345678123456781234567812345678 Supported Releases 10.4.0E(R1) or later area stub Defines an area as the OSPF stub area. Syntax Parameters area area-id stub [no-summary] • area-id-Set the OSPFv3 area ID as an IP address in A.B.C.D format or number, from 1 to 65535. • no-summary-(Optional) Prevents an ABR from sending summary LAs into the stub area. Default Not configured Command Mode ROUTER-OSPFv3 Usage Information The no version of this command deletes a stub area. Example OS10(config)# router ospfv3 10 OS10(conf-router-ospfv3-10)# area 10.10.1.5 stub Supported Releases 10.3.0E or later auto-cost reference-bandwidth Calculates default metrics for the interface based on the configured auto-cost reference bandwidth value. Syntax auto-cost reference-bandwidth value Parameters value - Enter the reference bandwidth value to calculate the OSPFv3 interface cost in megabits per second, from 1 to 4294967. Default 100000 Command Mode ROUTER-OSPFv3 Usage Information The value set by the ipv6 ospf cost command in INTERFACE mode overrides the cost resulting from the auto-cost command. The no version of this command resets the value to the default. Layer 3 705
