Modifying the Preemption Hold-Time Value for the VRRP Primary Router
The hold time is the maximum number of seconds that can elapse before a higher-priority backup router preempts the primary router. You might want to configure a hold time so that all Junos OS components converge before preemption.
By default, the hold-time value is 0 seconds. A value of 0 means that preemption can occur immediately after the backup router comes online. Note that the hold time is counted from the time the backup router comes online. The hold time is only valid when the VRRP router is just coming online.
To modify the preemption hold-time value, include the hold-time statement:
hold-time seconds;
The hold time can be from 0 through 3600 seconds.
You can include this statement at the following hierarchy levels:
[edit interfaces interface-name unit logical-unit-number family (inet | inet6) address address (vrrp-group | vrrp-inet6-group) group-id preempt][edit logical-systems logical-system-name interfaces interface-name unit logical-unit-number family (Inet | inet6) address address (vrrp-group | vrrp-inet6-group) group-id preempt]
