Cluster Cross subnet

Hi,

We currently have two independent clusters of F5 in separate subnets (sites) and require a method for synchronizing the configuration between them.

There is a restriction on the deployment where they must be in separate subnets. The two sites run active-active. The obvious issue for this is that the gateways are separate and when we attempt to synchronize the configuration, the gateway address is clobbered, resulting in the routing breaking.

We've tried a few things including:

• sync only; doesn't synchronize everything
• ip gw pool w/ sync fail-over; server split routing
• looking at the files manually and syncing them with external script

Does anybody have advice on how they would handle this situation?

Thanks.
