• Change the advertisement interval setting.
INTERFACE-VRID mode
advertise-interval seconds
The range is from 1 to 255 seconds.
The default is 1 second.
• For VRRPv3, change the advertisement centisecs interval setting.
INTERFACE-VRID mode
advertise-interval centisecs centisecs
The range is from 25 to 4075 centisecs in units of 25 centisecs.
The default is 100 centisecs.
Examples of the advertise-interval Command
The following example shows how to change the advertise interval using the advertise-interval command.
Dell(conf-if-te-1/1)#vrrp-group 111
Dell(conf-if-te-1/1-vrid-111)#advertise-interval 10
Dell(conf-if-te-1/1-vrid-111)#
The following example shows how to verify the advertise interval change using the show conf command.

Track an Interface or Object
You can set Dell Networking OS to monitor the state of any interface according to the virtual group.
Each VRRP group can track up to 12 interfaces and up to 20 additional objects, which may affect the priority of the VRRP group. If
the tracked interface goes down, the VRRP group's priority decreases by a default value of 10 (also known as cost). If the tracked
interface's state goes up, the VRRP group's priority increases by 10.
The lowered priority of the VRRP group may trigger an election. As the Master/Backup VRRP routers are selected based on the
VRRP group's priority, tracking features ensure that the best VRRP router is the Master for that group. The sum of all the costs of all
the tracked interfaces must be less than the configured priority on the VRRP group. If the VRRP group is configured as Owner
router (priority 255), tracking for that group is disabled, irrespective of the state of the tracked interfaces. The priority of the owner
group always remains at 255.
For a virtual group, you can track the line-protocol state or the routing status of any of the following interfaces with the interface
interface parameter:
• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port[/subport] information.
• For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information.
• For a port channel interface, enter the keywords port-channel then a number.
• For a VLAN interface, enter the keyword vlan then a number from 1 to 4094.
