Figure 142. 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.
Z-Series supports a total of 255 VRRP groups on a 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
