Figure 114. 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 decreases based on the dynamics of the network,
the advertisement intervals may increase or decrease accordingly.
