>From the perspective of Blue Box:

* Load balancing appliances will often (usually?) live outside the same
subnet as back-end member VMs.
* The network in which the load balancing appliances live will usually have
a default router (gateway)
* We don't anticipate the need for using extra_routes at this time, though
I suspect other operators might need this.
* We also anticipate occasionally needing the load balancing appliances to
have layer-2 connectivity to some back-end member VMs.
