/interface meshThe end goal is to be able to temporarily stand up any portion of this wireless network in the field and have those portions talk to each other.
Here's a basic diagram of what I have right now -
Here's a config from one of the wireless devices.

So far, so good. All the devices mesh with each other, get addresses from the DHCP server, and they can talk over IP.
Currently, I have the ether1 interface as a port in the mesh in each wireless device, so when I connect something to said port, it can talk to the rest of the mesh and gets an IP on the same subnet:
So far, this is alright, but it's still a bit centralized. If the router at 192.168.88.254 (or the wireless device it's physically conncted to) falls off the network, nobody will be able to talk because nobody will get an IP address.
I'd like to decentralize this, so for example I could take these two "sub-networks" and only connect them, but have them talk:
I'm having trouble conceptualizing this.
My initial thought is that each of the wireless devices' ethernet ports would be taken out of the mesh, and they'd have their own unique subnet (and DHCP server, etc). That takes care of each of the individual networks.
The next question is - how would the wireless devices get their addresses assigned? They'd probably have to be assigned unique static addresses on that 192.168.88.x subnet. That's doable.
Finally.... routing. Let's say the network now looks like this:
I'd like to not require a bunch of static routes on every device... so I assume I'd need to use some sort of dynamic routing protocol. If that's the case, what protocol would work over a wireless mesh and are there any special considerations?
If you made it this far - thanks for reading, and thanks in advance for the assistance!
