Configuring Basic VRRP Parameters
To implement a simple VRRP configuration using all the default values, enter commands such as the following.
Configuring the Owner
Router1(config)# router vrrp
Router1(config)# inter e 1/6
Router1(config-if-1/6)# ip address 192.53.5.1
Router1(config-if-1/6)# ip vrrp vrid 1
Router1(config-if-1/6-vrid-1)# owner
Router1(config-if-1/6-vrid-1)# ip-address 192.53.5.1
Router1(config-if-1/6-vrid-1)# activate
Dead interval The number of seconds a Backup waits for a Hello
message from the Master for the VRID before
determining that the Master is no longer active.
If the Master does not send a Hello message before
the dead interval expires, the Backups negotiate
(compare priorities) to select a new Master for the
VRID.
Three times the Hello
Interval plus one-half
second
22-4
22-16
Backup Hello
interval
The number of seconds between Hello messages
from a Backup to the Master.
The message interval can be from 60 – 3600
seconds.
You must enable the Backup to send the messages.
The messages are disabled by default on Backups.
The current Master (whether the VRRP Owner or a
Backup) sends Hello messages by default.
Disabled
60 seconds when
enabled

Track port Another Layer 3 Switch port or virtual interface whose
link status is tracked by the VRID’s interface.
If the link for a tracked interface goes down, the VRRP
or VRRPE priority of the VRID interface is changed,
causing the devices to renegotiate for Master.
None 22-5
22-17
Track priority A VRRP or VRRPE priority value assigned to the
tracked port(s). If a tracked port’s link goes down, the
VRID port’s VRRP or VRRPE priority changes.
• VRRP – The priority changes to the value of the
tracked port’s priority.
• VRRPE – The VRID port’s priority is reduced by
the amount of the tracked port’s priority.
VRRP – 2
VRRPE – 5
22-5
22-17
Backup preempt
mode
Prevents a Backup with a higher VRRP priority from
taking control of the VRID from another Backup that
has a lower priority but has already assumed control
of the VRID.
Enabled 22-17
