1.as re-directing the packets to layer 2 board interface, we must appoint the vlan of the out interface in flow-action, the correct configuration should be flow-action syf redirect ip 192.168.0.2 ethernet 2/0/0 vlan 200(the vlan that ethernet2/0/0 interface belongs to).
2.the destination address accessed by PC, it must be able to find the corresponding term in the routing table of NE40. such as the destination address accessed by PC is 172.16.10.1, there is one route in the routing table of NE40, whose destination network segment is 172.16.10.0/24. we can configure one static route manually 172.16.10.1
ip route 172.16.10.0 255.255.255.0 loopback 0
note the next hop cannot be Null interface, or configure one default route. Or configure one default route
ip route 0.0.0.0 0.0.0.0 the next-hop IP
