Pre-empting a Master
To configure a higher priority backup that can pre-empt a lower priority master, use
the ip vrrp preempt command in Interface Configuration mode, as shown below. If
virtual routers have IP addresses that do not belong to any router interface, use the ip
vrrp preempt command to specify which router may pre-empt. Use the no ip vrrp
preempt command to disable pre-emption of a lower priority master by a higher
priority backup.
MOT(config-if)#ip vrrp <number> preempt
where:
number is the VRID; valid values are 1 to 255.
Example
This example configures the system to pre-empt the current master on the configured
interface Ethernet slot 1, port 0 for VR1, which has been configured with a higher
priority. This command assumes the current master does not own the IP addresses of
virtual router 1.
interface ethernet 1/0
ip vrrp 1 preempt
Specifying Advertisement Interval
To specify the VRRP advertisement messages time interval, use the ip vrrp timer
command in Interface Configuration mode, as shown below. Use the no ip vrrp
timer command to restore the default of 1 second.
MOT(config-if)#ip vrrp <number> timer <interval>
where:
number is the VRID; valid values are 1 to 255.
Note: If the router owns the IP address or addresses associated with the
virtual router, the master always pre-empts, regardless of this command
setting.
