1.1.2 Introduction to Backup Group
I. Configurations available on switches in a backup group
VRRP can group switches in a LAN into a virtual router, which is also known as a
backup group.
You can perform the following configuration on an S3600 Ethernet switch that belongs
to a backup group.

II. Configuring switch priority
You can configure the priority of a switch in a backup group. VRRP will determine the
status of each switch in a backup group according to the priority of the switch. The
master switch in a backup group is the one currently with the highest priority.
Switch priority ranges from 0 to 255 (a larger number indicates a higher switch priority)
and defaults to 100. Note that only 1 through 254 are available to users. Switch priority
of 255 is reserved for IP address owners.
Note:
The priority of the IP address owner is fixed to 255.
III. Configuring preemptive mode for a switch in a backup group
As long as a switch in the backup group becomes the master switch, other switches,
even if they are configured with a higher priority later, do not preempt the master switch
