Users Guide

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
ipv6 ospf encryption
Congures OSPFv3 encryption on an IPv6 interface.
Syntax
ipv6 ospf encryption {ipsec spi number esp encryption-type key authentication-
type key | null}
Parameters
• ipsec spi number — Enter a unique security policy index number (256 to 4294967295).
• 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 algorithm to use (MD5 or SHA1).
• key — Enter the text string used in the authentication algorithm.
• null — Enter the keyword to not use the IPsec encryption.
Default IPv6 OSPF encryption 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.
