Currently I have two working software based A10 SoftAX vThunder load balancers that Inject Floating IP to two Juniper Hardware Firewall via OSPF to maintain HA. I am planning to get rid of A10s. I have added two new Centos vms and installed Haproxy on them that can do the load balancing. However, these two vms also need to do exactly what A10 vms are currently doing as far as the routing goes.
I am looking for an experienced System Administrator with strong Linux networking background who can install Quagga on these two vms and configure them to inject Floating IP to each Firewall via OSPF exactly the way A10 vms are currently doing. You also may need to twick among others ip route, Haproxy, nginx etc. to make the whole process to work.
