Example of the advertise-interval Command
Example of Verifying the Configured Advertisement Interval
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
Dell(conf-if-te-1/1-vrid-111)#show conf

Track an Interface or Object
You can set the 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:
• 10 Gigabit Ethernet: enter tengigabitethernet slot/port.
• Port channel: enter port-channel number.
• VLAN: enter vlan vlan-id where valid VLAN IDs are from 1 to 4094.
For a virtual group, you can also track the status of a configured object (the track object-id command)
by entering its object number.
NOTE: You can configure a tracked object for a VRRP group (using the track object-id command in
INTERFACE-VRID mode) before you actually create the tracked object (using a track object-id
command in CONFIGURATION mode). However, no changes in the VRRP group’s priority occur until the
tracked object is defined and determined to be down.
