VRRP in Load Balancing Mode

VRRP in Load Balancing Mode

In load balancing mode, multiple VRRP groups transmit service traffic simultaneously, as shown in Figure 7-5. The implementation and packet negotiation in load balancing mode are similar to those in active/standby mode. Each VRRP group has one master and multiple backups. In load balancing mode, multiple VRRP groups need to be set up and use different masters. A VRRP device can join multiple VRRP groups and has different priorities in different VRRP groups.

Multi-Gateway Load Balancing

Multiple VRRP groups with virtual IP addresses are created and specified as gateways for different users to implement load balancing.

Figure 7-5  Multi-gateway load balancing
As shown in Figure 7-5, two VRRP groups are configured:
  • VRRP group 1: RouterA functions as the master and RouterB as the backup.
  • VRRP group 2: RouterB functions as the master and RouterA as the backup.

VRRP groups 1 and 2 are gateways for different user hosts. Multiple VRRP groups load balance traffic and back up each other.
