Hi, Bishal In your case, STP is required to turn ON to close one of the ports to prevent bridge loops.
Refer to the bridge-loop-avoidance for the concept. http://www.open-mesh.org/wiki/batman-adv/Bridge-loop-avoidance > What do you mean by internal forwarding? This is the concept mentioned by Javier, internal forwarding (with zero cost) from 1st interface to 2nd interface and vice versa in single mesh node without bridging the interfaces.
