F5 sync options

Hi Manuel, do you try to setup a sync-failover device-group containing three units? To establish device trust I would recommend to force two units into offline state. Remove the machines from the existing sync-failover device-group (repeat on each machine if required) and delete the sync-failover device-group. Now reset the device trust on all machines. Next step will be to use the active machine to add both offline machines as peers. Now all three units should show up in each machine´s device list. On the active unit create a new device-group of type sync-failover with network failover enabled. Add all machines to the new device-group. This will be synced to all machines and you can release them from forced offline. Time for the initial sync now. Thanks, Stephan

Hi Stephan, We are trying to setup a sync-failover of four members, two in Miami that is the production environment, and two en Brasil that is the DR site. I have the same problem than Aaron, we can sync the two devices in both sites, but when we tried two create a trust domain of four devices we ran into problem. We have a sync network in both sites that is routed on MPLS, is not a connectivity problem. Once we add the third device to the trust domain, we lost the relation that we already have with the second member. Thanks
