Configuring with Web Based Management
5.6 The "Layer 3 (IPv4)" menu
● Master
If this option is enabled, the numerically lowest IPv4 address is entered for "Associated IP
Address". This means that the highest priority IPv4 address of the VRRP router is used as
the virtual IPv4 address of the virtual master router. The option must be disabled for the
backup routers in this group and the IP address of the router in "Associated IP address"
must be used.
● Priority
Enter the priority of this virtual router. Valid values are 1-255.
If an IPv4 address is assigned to the VRRP router that is also actually configured on the
local IPv4 interface, the value 255 is entered automatically. All other priorities can be
distributed freely among the VRRP routers. The higher the priority, the earlier the VRRP
router becomes "Master".
● Advertisement Interval
Enter the interval in seconds after which a master router sends a VRRP packet again.
● Preempt lower priority Master
Allow the precedence when changing roles between backup and master based on the
selection process.
● Track ID

"down" status.
