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-gi-1/1)#vrrp-group 111

Dell(conf-if-gi-1/1-vrid-111)#advertise-interval 10

Dell(conf-if-gi-1/1-vrid-111)#

The following example shows how to verify the advertise interval change using the show conf

command.

Dell(conf-if-gi-1/1-vrid-111)#show conf

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:

• 1 Gigabit Ethernet: enter gigabitethernet slot/port in the track interface command (shown in

the following example).

• 10 Gigabit Ethernet: enter tengigabitethernet slot/port.

• Port channel: enter port-channel number.

• SONET: enter sonet slot/port.

• VLAN: enter vlan vlan-id.
