Using VRRP to Implement Load Balancing

Using VRRP to Implement Load Balancing

VRRP active/standby is configured on a gateway to implement gateway redundancy. To reduce the burden of data traffic on the active device, VRRP load balancing can be used to load balance uplink traffic.

Multi-Gateway Load Balancing

Multiple VRRP groups with virtual IP addresses are created, with each VRRP group specified as a gateway for a user, implementing load balancing.

Figure 3-11  Multi-gateway load balancing
As shown in Figure 3-11, two VRRP groups are configured:
  • VRRP group 1: SwitchA functions as the master and SwitchB as the backup.
  • VRRP group 2: SwitchB functions as the master and SwitchA as the backup.

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