DVR does the ARP table update through the control plane, and does not allow any ARP requests to get out of the node. In order to address the allowed address pair VRRP IP issue with DVR, we need to add an ARP entry into the ARP Responder table for the allowed address pair IP ( which is taken care by the patch in [1]) This patch adds a rule in the br-int to redirect the packet destinated to the router to the actual router-port and also moves the arp filtering rule to the tunnel or the physical port based on the configuration. By adding the above rule it allows the ARP requests to reach the ARP Responder table and filters the ARP requests before it reaches the physical network or the tunnel.
