Supported Releases 10.3.0E or later ipv6 ospf authentication Configures OSPFv3 authentication on an IPv6 interface. Syntax Parameters ipv6 ospf authentication {null | ipsec spi number {MD5 | SHA1} key} • null - Prevents area authentication from being inherited on the interface. • ipsec spi number - Enter a unique security policy index number, from 256 to 4294967295. • md5 - Enable MD5 authentication. • sha1 - Enable SHA1 authentication. • key - Enter the text string used by the authentication type. Default IPv6 OSPF authentication is not configured on an interface. Command Mode INTERFACE Usage Information • • • • Before you enable IPsec authentication on an OSPFv3 interface, you must enable IPv6 unicast routing globally, configure an IPv6 address and enable OSPFv3 on the interface, and assign it to an area. The SPI value must be unique to one IPsec authentication or encryption security policy on the router. You cannot configure the same SPI value on another interface even if it uses the same authentication or encryption algorithm. You cannot use an IPsec MD5 or SHA1 authentication type and the null setting at same time on an interface. These settings are mutually exclusive. 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 SHA1 authentication, the non-encrypted key must be 40 hex digits. An encrypted key is not supported. Example OS10(config)# interface ethernet 1/1/6 OS10(conf-if-eth1/1/6)# ipv6 ospf authentication ipsec spi 400 md5 12345678123456781234567812345678 Supported Releases 10.4.0E(R1) or later ipv6 ospf cost Changes the cost associated with the OSPFv3 traffic on an interface Syntax ipv6 ospf cost cost Parameters cost - Enter a value as the OSPFv3 cost for the interface, from 1 to 65335. Default Based on bandwidth reference Command Mode INTERFACE Usage Information If not configured, the interface cost is based on the auto-cost command. This command configures OSPFv3 over multiple vendors to ensure that all routers use the same cost value. The no version of this command removes the IPv6 OSPF cost configuration. Example OS10(config)# interface vlan 10 OS10(conf-if-vl-10)# ipv6 ospf cost 10 Supported Releases 10.3.0E or later ipv6 ospf dead-interval Sets the time interval since the last hello-packet was received from a router. After the interval elapses, the neighboring routers declare the router dead. Syntax ipv6 ospf dead-interval seconds Layer 3 655
