VRRP Benefits
With VRRP configured on a network, end-station connectivity to the network is not subject to a single point-
of-failure. End-station connections to the network are redundant and are not dependent on internal gateway
protocol (IGP) protocols to converge or update routing tables.
VRRP Implementation
Dell Networking OS supports a total of 2000 VRRP groups on a switch and 255 VRRP groups per interface
Within a single VRRP group, up to 12 virtual IP addresses are supported. Virtual IP addresses can belong to the
primary or secondary IP address’ subnet configured on the interface. You can ping all the virtual IP addresses
configured on the Master VRRP router from anywhere in the local subnet.
