In this Example a single BalanceNG node is connected with one interface (“leg”) to one local Layer 2 network (LAN), which transports two Layer 3 IPv4 networks. The load balancing is configured between those two Layer 3 networks towards two target servers. It may be well used for getting started with BalanceNG concepts, but running two Layer 3 networks on a single Ethernet LAN may be confusing in the beginning. One advantage is, that there’s no need to change network topology like cables and switches. Runs with BalanceNG V3 and higher.
