One follow up question: When I do batctl o. It shows the MAC address of my network interface. In my case, is ah0. Not sure what to do in order to show the MAC address of the bat0.

Besides, when do batctl ping. I am using the MAC address of ah0. I can ping other node. If the MAC address is wrong, I think I cannot even ping another node, or traceroute to another node.

OK, Thanks for the clarification. Just wonder if there is any way to get the MAC address of bat0 on other end. For example: I got node A and node C. I want to send data packet from node A to node C. The MAC address of bat0 in nodeA is the source. Just wandering if there is a way to get the MAC address of bat0 in node C without physically show up in front of node C and run these commands.

So, if I understood correctly. The best way to do is to run command "ifconfig bat0" on both sides and fill in the HWAddr info accordingly.

Even though all my nodes are running batman-adv. I still do the same thing to obtain the MAC address of bat0. Is that right?

Now I switch to MAC address of bat0 as the source and destination address. In this case, I only have two nodes. Node A and node C. Now, I cannot send packet from node A to node C, and vice versa. However, when I do batctl tcpdump bat0 on the receiver side, I can see print out shown in the following. Warning - packet contains unknown ether type: 0x1337. Not sure what should I do now.

By looking at the packet.h from the batctl source code. I found this: #define BATADV_ETH_P_BATMAN 0x4305 /* unofficial/not registered Ethertype */ I guess it would be the packet type batman would recognized. When I set the type to 0x4305. However, I cannot even see any output from the receiver side when I run batctl tcpdump bat0 on it.
