2.3 Implementations in VRRP

You can control priorities of VRRP backup groups according to auto detect results to
enable automatic switch between the primary switch and the secondary switch as
follows:
Decrease the preference values of backup groups when the result of the detecting
group is unreachable.
Resume the preference values of backup groups when the result of the detecting
group is reachable.

2.3.1 Configuring Auto Detect for VRRP

Note:
You need to create a detecting group and perform VRRP configurations before the
following operations.
