The output shows that in VRRP group 1 LB A is the master, LB B is the backup and the host with the
default gateway of 202.38.160.111/24 accesses the Internet through LB A. In VRRP group 2 LB
A is the backup, LB B is the master and the host with the default gateway of 202.38.160.112/24
accesses the Internet through LB B.
NOTE:
To implement load balancing between the VRRP groups, be sure to configure the default gateway as
202.38.160.111 or 202.38.160.112 on the hosts on network segment 202.38.160.0/24.
VRRP load balancing mode configuration example
Network requirements
•
LB A, LB B, and LB C belong to VRRP group 1 with the virtual IP address of 10.1.1.1/24.
•
Hosts on network segment 10.1.1.0/24 use 10.1.1.1/24 as their default gateway. Use the VRRP
group to make sure that when a gateway (LB A, LB B, or LB C) fails, the hosts on the LAN can access
the external network through another gateway.
•
VRRP group 1 operates in load balancing mode to make good use of network resources.
•
Configure a track entry on LB A, LB B, and LB C to monitor their own GigabitEthernet 0/2. When
the interface on LB A, LB B, or LB C fails, the weight of the corresponding LB decreases so that
another device with a higher weight can take over.
