Reference 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 congured, the interface cost is based on the auto-cost command. This command congures 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 conguration.
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 conguration.
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
Congures 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 congured on an interface.
Command Mode INTERFACE
Usage Information
• Before you enable IPsec authentication on an OSPFv3 interface, you must enable IPv6 unicast routing globally,
congure an IPv6 address and enable OSPFv3 on the interface, and assign it to an area.
