View Interface view Default level 2: System level Parameters virtual-router-id: Virtual router ID or VRRP group number, which ranges from 1 to 255. timer delay delay-value: Sets preemption delay. The delay-value argument ranges from 0 to 255 seconds and defaults to 0 seconds. Description Use vrrp vrid preempt-mode to enable preemption on the router and configure its preemption delay in a specific VRRP group. Use undo vrrp vrid preempt-mode to disable preemption on the router in a specific VRRP group. As a result, the router operates in non-preemptive mode. Use undo vrrp vrid preempt-mode timer delay to restore the default preemption delay. By default, the router operates in preemptive mode and the preemption delay is zero seconds. To avoid frequent member state changes in a VRRP group and make the backups have enough time to collect information (such as routing information), each backup waits for a period of time (the preemption delay time) after it receives an advertisement with the priority lower than the local priority, then sends VRRP advertisements to start a new master election in the VRRP group and becomes the master. Before executing the command, create a VRRP group on an interface and configure the virtual IP address of the VRRP group. Related commands: display vrrp.

Parameters
virtual-router-id
:
Virtual router ID or VRRP group number, which ranges from 1 to 255.
timer delay
delay-value
: Sets preemption delay. The
delay-value
argument ranges from 0 to 255 seconds
and defaults to 0 seconds.
Description
Use
vrrp
vrid preempt-mode
to enable preemption on the router and configure its preemption delay in
a specific VRRP group.
Use
undo vrrp
vrid preempt-mode
to disable preemption on the router in a specific VRRP group. As a
result, the router operates in non-preemptive mode.
Use
undo vrrp vrid preempt-mode timer delay
to restore the default preemption delay.
By default, the router operates in preemptive mode and the preemption delay is zero seconds.
To avoid frequent member state changes in a VRRP group and make the backups have enough time to
collect information (such as routing information), each backup waits for a period of time (the preemption
delay time) after it receives an advertisement with the priority lower than the local priority, then sends
VRRP advertisements to start a new master election in the VRRP group and becomes the master.
Before executing the command, create a VRRP group on an interface and configure the virtual IP address
of the VRRP group.

# Enable preemption on the switch in VRRP group 1, and set the preemption delay to five seconds.
