Hierarchy Level

Description
Configure the number of fast advertisements that can be missed by a backup router before the primary router is declared as down.
The advertisement value configured using the
global-advertisements-thresholdstatement is applicable to all the Virtual Router Redundancy Protocol (VRRP) groups in the system.Setting the advertisement value of the global-advertisements-threshold configuration to 1 is not recommended for a scaled configuration with an aggressive advertisement interval. For example, if you have 1000 VRRP groups with an advertisement interval of 100 ms, then do not set the global-advertisements-threshold value to 1.
Changing the advertisement value of the global-advertisements-threshold configuration during runtime can result in unpredictable behavior by the VRRP state machine. For example, momentary ownership change from the primary router to the backup router and vice versa. Therefore, avoid changing the advertisement value of the
global-advertisements-thresholdstatement during runtime.
Options
