VRRP Load Balancing

VRRP Load Balancing

In load balancing mode, multiple devices transmit service traffic simultaneously. Therefore, the load balancing mode requires two or more virtual routers. Each virtual router contains one master and multiple backups, and the master in each virtual router can be different.

VRRP active/standby and load balancing modes are similar in terms of implementation and packet negotiation processes. The load balancing mode differs from the active/standby mode in the following ways:
  • Multiple VRRP groups need to be created, and the master in each VRRP group can be different.
  • A VRRP device can join multiple VRRP groups and has different priorities in different VRRP groups.

For an implementation example, see Using VRRP to Implement Load Balancing.
