Most functionality that is available in a single LoadMaster is available when a LoadMaster environment is clustered. The only restrictions are listed below:

  • All Virtual Services must operate at Layer 7

  • Transparency cannot be enabled

  • Subnet originating addresses are always enabled

  • Non-local Real Servers are not supported

  • HA mode cannot be used

  • VXLAN and IPsec tunneling are not supported

  • A 2-arm configuration is required

  • It is only possible to have a Virtual Service on the primary interface. Virtual Services on a second interface do not work.

  • GEO does not currently work properly when configured on a LoadMaster in clustering mode (as opposed to High Availability (HA) mode). If you want to use GEO with LoadMasters configured into clustering mode, GEO must be running as a standalone GEO Virtual Machine or configured on a LoadMaster that is not in clustering mode.
