VRRP Command Reference
If the priority command is not configured on the priority event, the priority value defaults to 0 and the
qualifier keyword defaults to delta with no impact on the in-use priority.
The no form of this command reverts to the default values.
Default
0
Parameters priority-level — specifies the priority level adjustment value
delta | explicit — configures what effect the priority level has on the base priority value
drop-count
Syntax drop-count consecutive-failures
no drop-count
Context config>vrrp>policy>priority-event>host-unreachable
Description This command configures the number of consecutively sent ICMP echo request messages that must
fail before the host unreachable priority control event is set.
The drop-count command is used to define the number of consecutive message send attempts that
must fail for the host unreachable priority event to enter the set state. Each unsuccessful attempt
increments the event consecutive message drop counter. With each successful attempt, the event
consecutive message drop counter resets to 0.
If the event consecutive message drop counter reaches the drop-count value, the host unreachable
priority event enters the set state.
The event hold-set value defines how long the event must stay in the set state even when a successful
message attempt clears the consecutive drop counter. The event is not cleared until the consecutive
drop counter is less than the drop-count value and the hold-set timer has a value of 0 (expired).

• if the sum of the delta priorities exceeds the delta-in-use-limit, then the delta-in-use-limit
value is used as the value subtracted from the base priority value defined on each virtual
router instance associated with the policy
Values 0 to 254
When delta is specified, the priority level value is subtracted from the base priority of the
associated virtual router instance when the event is set and no explicit events are set. The sum
of the priority event priority level values on all set delta priority events are subtracted from
the virtual router base priority to derive the virtual router instance in-use priority value. If the
delta priority event is cleared, the priority level is no longer used in the in-use priority
calculation.
When explicit is specified, the priority level value is used to override the base priority of the
virtual router instance if the priority event is set and no other explicit priority event is set with
a lower priority level. The set explicit priority value with the lowest priority level determines
the actual in-use protocol value for all virtual router instances associated with the policy.
