High availability on big ip 2600 device
ok, its an rSeries device. This failover port has no functionality on rSeries.
You need to configure tenants upon f5os. The HA will be built then from tenant to tenant. There is no bare metal installation anymore on rSeries.
Keep in mind you need 15.1.x or 17.1.x tmos release for the tenants. v16 is not supported on rSeries.
