I took this to heart and went back and checked everything again. Not too 
surprisingly, you were correct. But that's what you get for putting a Windows 
Developer onto a Linux box to do networking.

I finally resolved the networking issue and used a shell script to configure 
the batman after /etc/network/interfaces was fully completed. 

I will call this issue resolved, and start a new thread with my current issue. 
If anyone comes here as part of this discussion, look for my next post to see 
the current state of my configuration files. I know I hate it when people 
forget to post the actual answer.

Nearly correct - the eth1 IP configuration must also be removed because you 
configured two conflicting IP addresses (with the same subnet and metric) and 
in this process broke the routing table.

Why do you configure an IP address on eth1? It is part of a bridge and the IP 
configuration must be on top of the bridge. But you already have an IP
address in the same subnet configured on br0. There are ways to still work 
around this configuration problem but it would be weird to not simply fix the 
configuration.

Btw. this has nothing to do with batman-adv but is just about basic (Linux)
networking.

Kind regards,

I think I understand this to mean that I should remove the ipaddress, netmask 
configuration items from the bat0 interface, and create a bridge with bat0 and 
eth1. Something more like this for 10.1.1.1, and similar changes for 10.2.1.1

Please use either the actual mac address of the remote or the IP which is 
configured on the bat0 (which is also reachable directly by your host). 
batman-adv is not the IP subsystem and will therefore not be able to resolve 
any non-direct neighbors (over bat0).

Reach how? With IP routing? It is not the task of batman-adv to perform IP 
routing (it is on the wrong layer).

The IP configuration is weird. You have two IP addresses (bat0+ethX) which are 
overlapping (10.0.0.0/8). This cannot work.

If it should be a transparent bridge between mesh without IP routing then 
please add bat0+eth1 in the same bridge. And then configure the IP address on 
top of the bridge.

Kind regards,
Sven
