Configuring basic VRRP parameters
Configuring basic VRRP parameters
To implement a simple VRRP configuration using all the default values, enter commands such as
the following.
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that the Master is no longer active.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
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 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
Track priority
A VRRP or VRRPE priority value assigned to the tracked
ports. If a tracked port link goes down, the VRID port
VRRP or VRRPE priority changes:
•
VRRP – The priority changes to the value of the
tracked port priority.
•
VRRPE – The VRID port priority is reduced by the
amount of the tracked port priority.
VRRP – 2
VRRPE – 5
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
Timer scale
Adjusts the timers for the Hello interval, Dead interval,
Backup Hello interval, and Hold-down interval.
1
VRRP-E slow
start timer
This feature causes a specified amount of time to elapse
between the time the Master is restored and when it
takes over from the Backup. This interval allows time for
OSPF convergence when the Master is restored.
Disabled
