Vrrp Configuration; Configuration Task List - Dell S4048–ON Configuration Manual

CAUTION: Increasing the advertisement interval increases the VRRP Master dead interval, resulting in an increased failover time
for Master/Backup election. Take caution when increasing the advertisement interval, as the increased dead interval may cause
packets to be dropped during that switch-over time.
NOTE: In a VLT environment, VRRP configuration acts as active-active and if route is not present in any of the VRRP nodes, the
packet to the destination is dropped on that VRRP node.
