CHAPTER 19: Setting Up a High Availability System
4
If you plan to set up more than one primary/Standby
system in this subnet, delete the 3 in the HA Group ID
field and type a number that uniquely identifies this
system within the network context. (The number can
range between 3 and 255.)
HA Group IDs are used to identify High Availability Active/
standby pairs on your network. Each HA Active/Standby pair
should have a separate Group ID. You need to change this number
only if other devices are running the VRRP protocol (using the
same VRRP ID) on the networks connected to this appliance.
VRRP allows both HA security appliances to share the same
MAC and IP addresses.
