You can control the preferences of VRRP backup groups according to auto detect
results to enable automatic switch between the master and the backup switch as
follows:
Decrease the preference value of a VRRP backup group when the result of the
■
detecting group is unreachable.
Resume the preference of a VRRP backup group when the result of the detecting
■
group is reachable.
You need to create a detecting group and perform VRRP-related configurations
before the following operations.

Network requirements
Switch B and switch D form VRRP backup group 1, whose virtual IP address is
■
192.168.1.10.
Packets sourced from Switch A and destined for Switch C is forwarded by Switch B
■
under normal situations.
When the connection between Switch B and Switch C fails, Switch D becomes the
■
Master in backup group 1 automatically and the link from Switch D to Switch C,
the secondary link, is enabled.
