Hi shaikhzaid , 

please Review this Article about address lists with Virtual servers : 
https://techdocs.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/big-ip-ltm-virtual-servers-multiple-ip-port-14-1-0/01.html

I think it will not that hard in troubleshooting if you use it , but you should care about pool/pool members which this list of virtual servers forward traffic to , I mean you have to make sure your traffic flow for each virtual server ip in the address list.

But this is a good customization , it's good to test it first.

    Mohamed_Ahmed_Kansoh Thanks for the response.

    I have gone through the document and seems to be simple. I will apply it in our developement F5 node first.

    Also the policies and profiles specific to each VS, need to have a separate VS.

    Cordial.

      Hi shaikhzaid , 

      If you want to customize any profile you have to create a separte virtual server and add this customized profile to it. 
      Let me explain more. 

      If you have 100 Virtual servers have the same characteristics and properities you can rely on Address list , 
      But If you have 100 Virtual servers but with different characteristics and properities such as adding X-Forwarded-For or raising idle timeout values in TCP and ...etc of customizations you have to add them separetly.

        Thanks for the reply.

        Yes, i understood whilst reading the document. SInce we have several of the VS having customised policies to send to specific pool members so for those VS am keeping it separate.

        Including only those VS which is having only asm policies and other settings similar.
