Forward connections from particular network/vlan/iprange clients to specific pool member

I have four members in a pool. currently F5 LTM distributes the load to all the four members. but what I want is, distribute the load to 2 members, traffic from particular vlan clients to 3 member and another group of clients requests to 4th member. Any solution? ok to use multiple pools and irule etc., How could we achieve this? Thanks in advance.

    This is dead simple - you need to use different virtual servers with different parameters. VS1: Source includes the client subnet, pool includes member 4 VS2: VS enabled on specific VLAN only, pool includes member 3 VS3: VS enabled on all VLANs with no source address, pool includes members 1 & 2.

     

    Take a look here for VS precedence details

    Thanks Pete for your answer. Can all the clients with same Url(using only one VIP in the URL) achieve this? I forgot to mention all four members are Web servers(http requests to VS from clients)and users from different vlan should use same URL.

      Yes, you can create two VSs with the same IP and a different source for one of them. Obviously the rules of precedence will work then.
