If I've got a single network I would setup the load balancers/real servers as follows: 192.168.0.0/24: 192.168.0.5 - lvs01 192.168.0.6 - lvs02 192.168.0.10 - shared service VIP (via haresources) 192.168.0.15 - real server So I need to use 3 IP addresses, 2 for the load balancers and one for the VIP the load balancers present. I have several additional networks on which I want to provide the load balanced service, but one is a /28 so only provides 14 usable addresses. Is it required to have an IP for each load balancer on that network aswell as the service VIP, or can I just use the VIP on the networks eg: 10.249.16.128/28 (small network) 10.249.16.130 - lvs01 10.249.16.131 - lvs02 10.249.16.132 - shared service VIP 10.249.16.133 - real server Or for less IP use the load balancers don't have additional interfaces on the network, use the VIP to talk to the real servers: 10.249.16.132 - shared service VIP 10.249.16.133 - real server The second setup doesn't seem to work, I'm unsure why not (ARP issue), but I'm pursuing this because it saves 2/3 of the IP requirement on the small network.
