Configures subsecond intervals at which the master VRRP-Ev3 device advertises its existence to the backup routers.
The default advertisement interval scale is 1.
Virtual-router-group configuration mode
This command scales the advertisement interval of the master VRRP-Ev3 device as configured by the advertisement-interval command. A value of 1, 2, 5, or 10 can be set and the existing advertisement interval value is divided by the scaling value, for example, if the advertisement interval is set to 1 second and the scaling value is set to 10, the new advertisement interval is 100 milliseconds. When all the advertisement intervals in a VRRP-Ev3 session are scaled, subsecond VRRP-Ev3 convergence is possible if a master fails. The advertisement notifies the backup devices that the master is still active. If the backup devices do not receive an advertisement from the master in a designated amount of time, the backup device with the highest priority can assume the role of master. Using subsecond advertising intervals, subsecond device redundancy can be achieved.
This command is only supported by VRRP-Ev3.
To set the scaling of the advertisement interval to 500 milliseconds for VRRP-Ev3 group 19:
