Hi batman-adv community,
We have been building openwrt 15.05 + batman-adv mesh network for over 2 years, they work great.
We are planning to use batman-adv gateways + 4G modems. For an example: our mesh network is with 20 nodes, 3 nodes have 4G modems connected.
1) My first thought is to use batman-adv gateway (with 4G modem connected) as dhcp server, and forward batman-adv interface to wan interface (modem). 1.1) But, there is an issue with this setup. Once a modem is down, nodes that are connected to this batman-adv gateway (with modem) can not automatically "roam" to another batman-adv gateway (with good modem connection). 1.2) This behavior is expected, right?
2) My second thought is to bridge batman-adv interface and wan interface (modem). This works great, I do not see issue (1.1) above. - By this setup, all batman-adv clients get ip via dhcp and via modem. 2.1) Is this the suggested setup to use batman-adv gateways?
3) When I bridge batman-adv interface with other interface (as in step 2 above), can I use batman-adv interface via *ipv6* to ping other batman-adv nodes?
Thanks. Xuebing Wang
