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,
