30.3.8 Enable or Disable VRRP Master Preemption
Syntax [no] preempt [delay <0..1000>]
Context VRRP Instance Configuration context
Usage Enable or disable VRRP master preemption. If enabled, this router will
preempt an existing master if the current master has lower priority. (Note:
The owner of a VIP address will always take over as master irrespective of
the ”preempt” setting.)
When preemption is enabled, the router will wait a time interval depend-
ing on the configured advertisement interval and a configurable preemption
delay (seconds) before taking over as master.
Note
Preemption only occurs when starting or restarting a higher priority
backup router, e.g. if a link down event occurs preemption will not be
used.
Note
Note: When the instance belongs to a synchronized group, the instance
with the shortest preemption delay will be used.
Use ”no preempt” to prohibit this router to preempt an existing VRRP mas-
ter.
Use ”show preempt” to show the configured VRRP master preemption set-
ting for this VRRP instance.
Default values Disabled (”no preempt”) When enabled, the delay defaults to
0 seconds.
30.3.9 Configure VRRP Message Authentication
Syntax [no] auth <plain> <SECRET>
Context VRRP Instance Configuration context
Usage Configure VRRP message authentication. Simple clear-text authentica-
tion is supported for VRRP version 2.
