active active setup for bigip

I am trying to setup an active-active setup with a pair of bigip devices. I have some questions.. 1> how many floating self-ips and non-floating self-ips are required for at a minimum for each vlan? 2> can different virtuals from the same vlan be there on different units or the same unit? 3> does pool member monitoring still work like in active-standby setup viz., like non-floating selfip getting status of pool members and floating ip processing traffic....

    Hi,

     

    The following answers are for version 11.x, the cluster behavior is different in previous versions.

     

    1. For each VLAN :

       

      • 1 self IP is required per Big IP
      • For routing needs, 1 floating IP is needed per Traffic Group on each VLAN

    2. Virtual servers are not defined on units, Virtual address are defined on traffic group (traffic group 1 by default). there is no limitation on VLAN / Traffic groups

       

    3. Pool members are monitored with non floating self IP

       

    Active / Active cluster is configured with 2 traffic groups acting as Active / Passive Cluster. to convert a Active / Passive Cluster to an Active / Passive cluster, you need to :

     

    • create a traffic group (traffic-group-2)
    • create floating self IPs in traffic-group-2 (used to SNAT automap)
    • change virtual address traffic group to traffic-group-2

    Is there any particular guide you can point me to which shows how to setup active - active setup ? things like creating traffic groups and device groups.
