Reference Guide

Usage Information The no version of this command removes an interface from an OSPFv3 area.
Example
OS10(config)# interface vlan 10
OS10(conf-if-vl-10)# ipv6 ospf 10 area 1
Supported Releases 10.3.0E or later
ipv6 ospf authentication
Congures OSPFv3 authentication on an IPv6 interface.
Syntax
ipv6 ospf authentication {null | ipsec spi number {MD5 | SHA1} key}
Parameters
• null — Prevents area authentication from being inherited on the interface.
• ipsec spi number — Enter a unique security policy index number (256 to 4294967295).
• md5 — Enable MD5 authentication.
• sha1 — Enable SHA-1 authentication.
• key — Enter the text string used by the authentication type.
Default IPv6 OSPF authentication is not congured on an interface.
Command Mode INTERFACE
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

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.
