VRRP and VRRP-E parameters
Dead interval
The number of seconds or milliseconds 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determining that the Master is no longer active.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.
The dead interval
calculation for VRRP
v6 or VRRP-E v6 is:
Dead Interval: ( 3 X
Hello Interval ) +
Skew Time
Skew Time is 256 -
Priority X Hello
Interval / 256.
For VRRP v3, the
default is 3600
milliseconds. The
configurable range is
from 100 through
8400 milliseconds.
For VRRP-E v3, the
default is 3600
milliseconds. The
configurable range is
from 1 through 84
seconds.
Backup Hello
interval
The number of seconds between Hello messages from a
Backup to the Master.
The message interval can be from 60 through 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
VRRP-E priority of the VRID interface is changed, causing
the devices to renegotiate for the Master.
NOTE: Track port is not supported by VRRP v3.
None
Track priority
A VRRP or VRRP-E priority value assigned to the tracked
ports. If a tracked port link goes down, the VRID port
VRRP or VRRP-E priority changes:
•
VRRP – The priority changes to the value of the
tracked port priority.
•
VRRP-E – The VRID port priority is reduced by the
amount of the tracked port priority.
NOTE: Track priority is not supported by VRRP v3.
VRRP – 2
VRRP-E – 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.
NOTE: The timer scale is not supported for IPv6 VRRP v3.
