Here's my shitty first attempt at diagram to illustrate how it all hangs together with vlan, bridging and tunnels:

The
big thing in the middle is a home node. The chunky things sticking out
of it to the left are antennas. The two things on the right are extender
nodes.
The numbers are VLAN IDs. As you can see there is one
VLAN for the open network (VLAN 10), one VLAN for the private network
(VLAN 11) and then one VLAN per extender node for the mesh network
(VLANs 1 and 2).
You can see that the private and
public network interfaces are connected together between wifi, ethernet,
home and extender nodes by putting the interfaces on the same VLAN (for
ethernet) and then bridging to the wifi interfaces.
The
mesh network interfaces are connected together by enabling babeld on
all of them, or in the case of the connection between home and extender
nodes they are connected by being on the same VLAN.
On
this diagram all three networks are available on all radios both on
home and extender nodes. This is not yet fully implemented, but it is a
small enough change that we should be able to finish it this week.
