NimbostratusUneven Loadbalancing across Proxy
Hi,
I have an issue load balancing traffic across 2 bluecoat proxy. I'm using dest_addresss for persistance and RR for load balancing. Load balancing is not happening - all the traffic is going to the second node in the pool and nothing to the first node. What is the best persistance method that can be used here? I want both the proxy to be utilized.
regards, Parvez

Please change the Pool LB method from RR to Least connection and try any persistence method. Hope issue will solved.
Does it makes sense?

Hi,
This is normal behavior when using destination address persistence. I guess that your VIP is with /32 mask and in that case you have only one destination. Thats why every time the persistence is choosing only one of your backend servers.
If you need persistence you can use source address or cookie based, but that depends on your network design. For example if you have a proxy before F5 and all the reqeusts are comming with the same IP address, the source address persistence will not work for you.
Have in mind that when you are using persistence it will affect the load balancing method. And even when you have round-robin, the traffic will be never equal on the backend servers.
