Enable pre-emption:
set interfaces ethernet eth0 vrrp vrrp-group
<VRRP GROUP #> preempt true
4.
Set the priority of this ACM:
set interfaces ethernet eth0 vrrp vrrp-group
<VRRP GROUP #> priority <PRIORITY #>
Important:
Make sure to set a higher priority for the master ACM than the priorities for all
backup ACMs.

Configuring the Master and Backup ACMs with a Sync
Group
Sync Groups are identified by a unique string that is configured using the steps
below (for example, "ALPHA", "MyGROUP" etc).
To configure the master ACM and each backup ACM with a sync group, do the
following for each ACM:
1.
Add the sync group configuration to the existing configuration for a VRRP
group on eth0:
set interfaces ethernet eth0 vrrp vrrp-group
<VRRP GROUP #> sync-group <SYNC GROUP NAME>
2.
Display the VRRP configuration on eth0 (optional):
show interfaces ethernet eth0 vrrp
3.
Create the VRRP configuration node for eth1 on the ACM to enable VRRP on
that interface; assign the VRRP group:
set interfaces ethernet eth1 vrrp vrrp-group
<VRRP GROUP #>
4.
Specify the virtual address of the VRRP group:
set interfaces ethernet eth1 vrrp vrrp-group
<VRRP GROUP #> virtual-address <VIRTUAL INSIDE-
IPADDRESS/SUBNET>
5.
Enable preemption:
set interfaces ethernet eth1 vrrp vrrp-group
<VRRP GROUP #> preempt true
6.
Set the priority of this ACM—Make sure to set a higher priority for the master
ACM than the priorities for all backup ACMs:
set interfaces ethernet eth1 vrrp vrrp-group
<VRRP GROUP #> priority <PRIORITY #>
