Thanks Erik.

But shouldn't the VIP be from the associated tenant network?

I need to configure reaching the VIP from another external host.
Currently, the VIP is being assigned from a link local network, which
is not reachable externally. I took a quick look at the code and this
network looks hard coded. Am I missing something?

Thanks
