[B.A.T.M.A.N.] MAC address for BAT0 Intefrace

Hello All,

I saw in the batman-adv code that random MAC address is being assigned to BAT0 Interface. I need some clarification regarding this.

I have tested the following tests, Test Scenarios: Batman_Node_ A (192.0.0.1) ---------------------- Batman_Node_B (192.0.0.2)

Test 1: First, I used batman code without any change. I used eth_hw_addr_random () for BAT0 MAC assignment. Result: I am able to ping from node A to Node B

Test 2: I commented “eth_hw_addr_random ()” and assigned MAC address of primary interface to BAT0 interface at both nodes. Now, we have same MAC for primary interface and BAT0 at both nodes. Result: I am able to ping from node A to Node B

As you guys have assigned the random MAC to BAT0 interface, I wanted to know that what would be potential problems if we assign the MAC addresses of primary interface to the bat0 interface.

Thanks in advance.

Thanks Ajeet
