The LB are Never BEEN the network,(layer 2/3/4 )switch.
Modern BIG comercialy Build Linux LVS like from loadbalancer.org have an
switch build in the appliance ( great stuff ..) .
To build an Simple selfowned & selfmanaged - this are not an requirement.
my damn Homecluster LB L2/L3 switch here at home has cost 10 eur i.e :-) - ok
you won´t service PRod with that - but it works.
Regulary with LVS DR .. LB´s and Realservers been connected to the SAME
Network using the same network( layer 2/3 )switch(s).
This can be streched across Datacenters over VLAN & VPN usage.
