Dell S4820T - VRRP Benefits; VRRP Implementation

Figure 136. Basic VRRP Configuration
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
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.
The S4820T supports varying number of maximum VRRP groups per interface. The S4820T supports a
total of 2000 VRRP groups on a switch and 512 VRRP groups per interface.
