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.

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.

The following recommendations shown may vary depending on various factors like address resolution

protocol (ARP) broadcasts, IP broadcasts, or spanning tree protocol (STP) before changing the

advertisement interval. When the number of packets processed by RP2/CP/FP processor increases or
