Configuring the F5 LTM load balancer

The following procedures demonstrate how to configure a load balancer to implement session persistence with Bravura Security Fabric . Testing has been done against the F5 BIG-IP load balancer.

Requirements

Before starting, ensure that the following prerequisites have been met:

  • BIG-IP F5 Load balancer licensed for Local Traffic Management. Version 13.1.1 in a single-NIC configuration was used for this testing.

  • Bravura Security Fabric instances installed in replication.

  • The load balancer, Bravura Security Fabric instances, and all client and target systems have connectivity to each other.

  • The BIG-IP load balancer’s management port is on a network or subnet that is separate from the Bravura Security Fabric instances or their client and target systems.

  • The BIG-IP Setup utility has been run to configure initial settings

  • The BIG-IP system has network interface, VLAN, server pool, and self IP configurations in place to direct traffic to and from Bravura Security Fabric nodes.
