Figure 130. 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.
Up to 255 VRRP groups are supported on the switch. The total number of VRRP groups per system 
should be less than 512.
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
