Thank you Damjan, The my-forwarder plugin performs l3 lookup (3D array - on some bytes of the dest-IP (v6) and decides about the output interface. then sends to interface-output node - this works perfectly (with static arp/ndp installed in the dest/source machines) when dest-ip and src-ip are in the same subnet. i need a solution for: - not in the same subnet - ARP/NDP responder - i will cancel the static ARP/NDP
please tell me if you need more details.
