Vrrp Vrid Priority - 3Com S7906E Command Reference Manual

Parameters
virtual-router-id: Virtual router ID or VRRP group number, in the range 1 to 255.
timer delay delay-value: Sets preemption delay. The delay-value argument is in the range of 0 to 255
seconds and defaults to 0 seconds.
Description
Use the vrrp vrid preempt-mode command to enable preemption on the switch and configure its
preemption delay in the specified VRRP group.
Use the undo vrrp vrid preempt-mode command to disable preemption on the switch in the specified
VRRP group.
Use the undo vrrp vrid preempt-mode timer delay command to restore the default preemption delay,
that is, zero seconds.
The default mode is immediate preemption without delay.
To avoid members in a VRRP group from changing their states frequently and make 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 finally
becomes the master.
Note that before executing the command, you need to create a VRRP group on an interface and
configure the virtual IP address of the VRRP group.
Examples
# Enable preemption on the switch in VRRP group 1, and set the preemption delay to five seconds.
