[ no ] ip vrrp vrid timers-learn
Command introduced in JunosE Release 10.3.0.
Configures the VRRP instance to learn the VRRP advertisement interval from the master VRRP instance. This feature is useful only when you have configured different advertisement intervals for the master VRRP instance and the backup VRRP instance. This feature enables the unified ISSU operation to proceed successfully. The no version disables the learning timer for the VRRP instance. If you have configured different advertisement intervals for the VRRP master and VRRP backup instances, the VRRP session breaks, and both instances behave like the master instance, and the router displays an error message.
