With load balancing, several routers exist which can accomplish the same tasks. These routers are pronounced to be the default gateway and evenly distributed among the computers in the LAN using the DHCP server active in every router. If one of the routers fails, then another can take over its functions providing both routers work with VRRP. On every router, as many virtual routers are defined as there are actual routers. The computers in the LAN are assigned one of the virtual routers as a gateway. Using the virtual router priorities, it is now defined in which order the other routers take over when a master fails. It is also possible to establish a backup chain using the main and backup priority here.
