Feb 14, 2015Hi Aaron,
the initial post an my response seem to be gone. So sorry for repeating myself partially.
"Sync-only" will not allow to synchronize LTM configurations.
To synchronize an LTM config all units need to belong to the same "sync-failover" device-group.
A traffic-grpup containing the virtual failover objects can be active on a single device in the device-group only.
So if you want both sites to be active (running the local devices in active/standby) it would be necessary to use a "sync-failover" device group of four devices with two traffic-groups.
A virtual address can be assigned to a single traffic-group only.
The only workaround would be using routing domains. Overlapping IPs are permitted.
But it adds complexity and each service still has to be configured twice (in each routing domain).
That´s why I would consider to use i.e. the new REST based iControl API to modify two independent "sync-failover" device-groups simultaneously.
Thanks, Stephan
