Configuring VRRP Services

1-4

304138-A Rev 00

The configuration in Figure 1-2 shows that half of the hosts install a default route

to VRRP router A’s IP address (1.1.1.1), and the other half install a default route to

VRRP router B’s IP address (2.2.2.2). Using two different default routes has the

effect of load-balancing the outgoing traffic, while also providing full redundancy.
