Chapter 1 Configuring IPv6 Unicast Routing
Configuring IPv6
Use the no standby [ group-number ] ipv6 interface configuration command to disable HSRP for IPv6.
This example shows how to activate HSRP for IPv6 for group 1 on a port. The IP address used by the
hot standby group is learned by using HSRP for IPv6.
Note
This procedure is the minimum number of steps required to enable HSRP for IPv6. Other configurations
are optional.
Switch# configure terminal
Switch(config)# interface gigabitethernet1/0/1
Switch(config-if)# no switchport
Switch(config-if)# standby 1 ipv6 autoconfig
Switch(config-if)# end
Switch# show standby
For more information about configuring HSRP for IPv6, see the “Configuring First Hop Redundancy
Protocols in IPv6” chapter in the
Cisco IOS IPv6 Configuration Library on Cisco.com.
Step 4
standby [ group-number ] preempt [ delay
{minimum seconds | reload seconds | sync
seconds }]
Configure the router to preempt , which means that when the
local router has a higher priority than the active router, it
assumes control as the active router.
•
(Optional) group-number —The group number to which the
command applies.
• (Optional) delay —Set to cause the local router to postpone
taking over the active role for the shown number of seconds.
The range is 0 to 3600 (1 hour). The default is 0 (no delay
before taking over).
•
(Optional) reload —Set the preemption delay, in seconds,
after a reload. The delay period applies only to the first
interface-up event after the router reloads.
• (Optional) sync —Set the maximum synchronization
period, in seconds, for IP redundancy clients.
Use the no form of the command to restore the default values.
Step 5 standby [ group-number ] priority priority Set a priority value used in choosing the active router. The
range is 1 to 255; the default priority is 100. The highest number
represents the highest priority.
Use the no form of the command to restore the default values.
Step 6 end Return to privileged EXEC mode.
Step 7 show standby [ interface-id [ group-number ]] Verify the configuration.
Step 8 copy running-config startup-config (Optional) Save your entries in the configuration file.
