Loopback Loadbalancing

Hi

 

 

Can anybody direct me or explain me a little here how can i go about with the configuration (Vlans, etc) and design with the following scenario

 

 

There is one BIGIP and i have two sets of web servers, application servers and database servers.

 

So for any application there would be two redundant webservers, two application servers and two database servers.

 

Now we are using BIGIP LTM (Loadbalancers).

 

 

How can i go about the configuration so that i have the web services, then their respective application services and database services loadbalanced.

 

 

here One application server (Application 1) will talk to other application server (Application 2) very frequently while talking to its database at the same time.

 

 

Respective webserver will talk to its own application server only.

 

 

Thanks

    There is no technical reason why the servers can't all be in the same vlan, but do you have security requirements that would demand their separation? Any other requirements or more detailed application flows would help in assessing your situation.

    I want them to be in the same vlan (Layer 2 Adjacency). I was talking about the internal, external vlans.

     

    I want to know how can i go about the loopback configuration, when webserver requests are loadbalanced and when the request from the webserver has to goto application server, it again goes to the same Loadbalancer, goes to the application server and then again goes to the same LB to loadbalance for databases
