Reference Guide

Usage Information
• Before you enable IPsec authentication on an OSPFv3 interface, you must enable IPv6 unicast routing globally,
congure an IPv6 address and enable OSPFv3 on the interface, and assign it to an area.
• The SPI value must be unique to one IPsec security policy (authentication or encryption) on the router. You
cannot congure the same SPI value on another interface even if it uses the same authentication or encryption
algorithm.
• You cannot use an IPsec authentication type (MD5 or SHA-1) 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 SHA-1
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

Supported Releases 10.4.0E(R1) or later
ipv6 ospf cost
Changes the cost associated with the OSPFv3 trac on an interface
Syntax
ipv6 ospf cost cost
Parameters cost — Enter a value as the OSPFv3 cost for the interface (1 to 65335).
Default Based on bandwidth reference
Command Mode INTERFACE
Usage Information If not congured, the interface cost is based on the auto-cost command. This command congures 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 conguration.
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
Parameters seconds — Enter the dead interval value in seconds (1 to 65535).
Default 40 seconds
Command Mode INTERFACE
Usage Information The dead interval is four times the default hello-interval by default. The no version of this command removes the
IPv6 OSPF dead-interval conguration.
Example
OS10(config)# interface vlan 10
OS10(conf-if-vl-10)# ipv6 ospf dead-interval 10
Supported Releases 10.3.0E or later
