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
