Where to find reference on exact commands?
The bridge-utils-interface man pages describe the options.
Create and link to article covering fundamental bridging btw existing network interface... the original use of a bridge.
Creating a Simple Bridge
I'm frankly still fuzzy on what's happening here. But this bridge works for my LXD host to allow my containers to interface with my hosts network directly.
Here is the default dhcp network interface...
Here is the network interface with modifications to make it static...
Here is we've added a bridge br0 that interfaces with the host's primary network card ens3,
