Does batman-adv  support gateway ? Should all nodes' interfaces(batman-adv interface , non batman-adv interface) be in the same network(e.g. 192.168.1.0/24)   or  use "HNA" to announce different networks? (some nodes have multi interfaces)

Olsrd can use "HNA" to announce  'non-olsrd interface' in different network  from 'olsrd interface' , so other nodes know how to get to that network.

How to config the IP address of a node with two interfaces running batman-adv at the same time?

Hey,

are sure you want to know about batman-adv ? Advanced operates on layer 2 (mac 
address layer) and does not care about IP addresses. If you want to let non-
batman nodes join the network you simply bridge the interfaces. No (manual) 
HNA settings are needed.

If you are interested in the batman daemon (layer 3 - ip layer) I suggest you 
read through our documentation: http://www.open-mesh.net/wiki/UserDocs

Regards,
Marek

Thank you for your reply!
I just used olsrd. I am a newbie for BATMAN. I want to try it.

From open-mesh.net and your description I almost know batman-adv is on layer 2 . But some applications need IP addresses, 
so use DHCP server to allocate IP address in the same network, or config manually?
Could you give me a guide document about setting and config steps of a mesh network  (about 30 nodes) using batman-adv  in detail. 

in "README" :
# insmod batman-adv.ko
# echo wlan0 > /proc/net/batman-adv/interfaces
The module will create a new interface 'bat0'

What's the difference between 'wlan0' and 'bat0'? 
Should I bridge the non-batman interface (e.g. eth0 ...) with 
bat0 or wlan0 ?   config the IP address of wlan0 , bat0 separately ?

Hello Wu,

you can set an IP address on the bat0 interface, or include it in a bridge 
with eth0 or other devices which are not used for the mesh. You might as well
use DHCP to provide addresses to your nodes (which is not possible with layer 3
daemons, btw). You don't need to set IP addresses of the "base interfaces" 
which are used by batman - just make sure they are up (ifconfig wlan0 up).
The bat0 interface can be used like any other ethernet-compatible network
interface - you can consider it as port to a virtual distributed switch.

best regards,
	Simon
