NOTE: To set the interval time between the reception of topology changes and calculation of SPF in milli seconds, use the
timers spf delay holdtime msec command.
Example
Dell#conf
Dell(conf)#ipv6 router ospf 1
Dell(conf-ipv6-router_ospf)#timer spf 2 5 msec
Dell(conf-ipv6-router_ospf)#
Dell(conf-ipv6-router_ospf)#show config
!
ipv6 router ospf 1
timers spf 2 5 msec
Dell(conf-ipv6-router_ospf)#
Dell(conf-ipv6-router_ospf)#end

Enabling IPv6 Unicast Routing
To enable IPv6 unicast routing, use the following command.
• Enable IPv6 unicast routing globally.
CONFIGURATION mode
ipv6 unicast routing
Applying cost for OSPFv3
Change in bandwidth directly affects the cost of OSPF routes.
• Explicitly specify the cost of sending a packet on an interface.
INTERFACE mode
ipv6 ospf interface-cost
• interface-cost:The range is from 1 to 65535. Default cost is based on the bandwidth.
• Specify how the OSPF interface cost is calculated based on the reference bandwidth method. The cost of an interface is calculated as
Reference Bandwidth/Interface speed.
ROUTER OSPFv3
auto-cost [reference-bandwidth ref-bw]
To return to the default bandwidth or to assign cost based on the interface type, use the no auto-cost [reference-
bandwidth ref-bw] command.
• ref-bw: The range is from 1 to 4294967. The default is 100 megabits per second.
Assigning IPv6 Addresses on an Interface
To assign IPv6 addresses to an interface, use the following commands.
1 Assign an IPv6 address to the interface.
CONF-INT-type slot/port mode
ipv6 address ipv6 address
IPv6 addresses are normally written as eight groups of four hexadecimal digits; separate each group by a colon (:).
656
