Figure 148. 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
The S5000 supports a total of 255 VRRP groups on a switch.
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 recommendations in the following table may vary depending on various factors like ARP broadcasts,
IP broadcasts, or 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.
