Bridging Veras

How do I bridge two (or more) Veras?

Is there a limit to the number of Veras that can be bridged?

Do bridged Veras require an internet connection?

My setup is a little different. My mesh extends through the whole house, so I only have one network. Also, I wanted to set up my vera1 as my programming box… to test code before I load on my vera2. So instead of bridging veras, I added my vera1 dongle as a secondary to my vera2, added all my devices to vera2, and taught/learned them back to my vera1. They communicate through z-wave regularly and seem to be working fairly well.
For my door sensor, I had to associate the sensor in group 1 with both veras. The status now appears correctly in both veras, but on my secondary vera (vera1), it constantly says “Waiting for wakeup to configure device”. I turned off automatic configuration of the sensor on the secondary vera, but it still says that. Don’t know what else to try. Any thoughts?
