Vrrp Ipv6 Vrid Priority - 3Com S7906E Command Reference Manual

Description
Use the vrrp ipv6 vrid preempt-mode command to configure preemption on the switch and configure
its preemption delay in the specified VRRP group.
Use the undo vrrp ipv6 vrid preempt-mode command to disable preemption on the switch in the
specified VRRP group.
Use the undo vrrp ipv6 vrid preempt-mode timer delay command to restore the default preemption
delay, that is, zero seconds.
The default mode is immediate preemption without delay.
If you set the switch in the VRRP group to work in non-preemptive mode, the delay period changes to
zero seconds automatically.
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 IPv6 address of the VRRP group.
Examples
# Enable preemption on the switch in VRRP group 80 and set the preemption delay to five seconds.
