The output shows that Switch A is operating as the master in VRRP group 1 to forward Internet
traffic for hosts that use the default gateway 10.1.1.100/25, and Switch B is operating as the
master in VRRP group 2 to forward Internet traffic for hosts that use the default gateway
10.1.1.200/25.
VRRP load balancing configuration example
This section provides an example of configuring the VRRP load balancing mode.
Network requirements
Switch A, Switch B, and Switch C form a load-balanced VRRP group and use the virtual IP address
10 .1.1.1 / 2 4 t o p r o v i d e g a t e w a y s e r v i c e f o r s u b n e t 10 .1.1. 0 / 24 , a s s h o w n i n Figure 28.
Co
nfigure VFs on Switch A, Switch B, and Switch C to monitor their respective VLAN-interface 3. When
the interface on any one of them fails, the weights of the VFs on the problematic switch decrease so
another AVF can take over.
