The advertisement interval specifies the time until a virtual router is propagated again. The default value is 100 centiseconds (1 second).
Additionally, version v2 or v2+v3 require the interval to be an integer of 100, since for VRRPv2 the interval must be an integer number of seconds. If the version is subsequently changed, the advert interval is automatically adjusted to a valid value and should be checked.
Note: With a propagation time of 1 second, the routers in the VRRP group can change quickly when a device or interface fails. An interruption of this type will usually remain undetected due to the fact that the TCP connection is not interrupted. Other routing protocols require up to 5 minutes or longer in order to conduct the transfer to a backup router.
