Static Routing between Child / Parent Route Domains

My guess is that by having something in the parent domain, when a node using the F5 as a gateway tries to access something directly attached to the F5 in that parent domain, the F5 will swing the traffic to that VLAN/interface. The route on the F5 ( child/parent ) won't come into play since the traffic is allowed to flow freely.

If that doesn't work, you should be able to add a route in each child domain to a default gateway in the shared parent domain.

I'm curious as to how this works. My gut says the first way.
