• Router State
Shows the current status of the virtual router. Possible values are:
– Master
The router is the Master router and handles the routing functionality for all
assigned IP addresses.
– Backup
The router is the backup router. If the master router fails, the backup router takes
over the tasks of the master router.
– Initialize
The virtual router has just been turned on. It will soon change to the "Master" or
"Backup" state.
• Master IP Address
Shows the IPv4 address of the master router.
• Priority
Shows the priority of the virtual router.
Valid values are 1-254.
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".
• Advert. Interval
Shows the interval at which the master router sends VRRP packets.
• Preempt
Shows the precedence of a router when changing roles between backup and master.
– yes
This router has precedence when changing roles.
– no
This router does not have precedence when changing roles.
VRRP and DHCP server
If you want to operate a DHCP server on the devices of a VRRP group, the DHCP server
must be configured on the master router. Backup routers do not react to DHCP queries.
Make sure that the master router is statically configured and that after a failure,
becomes the master of the VRRP group again.
Steps in configuration
1. Select the "VRRPv3" check box.
2. Select the required interface.
3. Enter the ID of the virtual router in the "VRID" input box.
4. Click the "Create" button. A new row is inserted in the table.
5. Select the "Reply to pings on virtual interfaces" check box so that virtual addresses
reply to pings as well.
