The configuration policy route is invalid when NE40 L2 acts as the next-hop egress of policy route.
1. Check the configuratoin and find that the next-hop of policy route is L2 egress.
2. Check configuration again and only flow-action fcnc redirect ip ×.×.×.× GigabitEthernet4/1/1 is configures when configuring flow-action and not designate VLAN of VLAN 156. The service is not reachable.
3. Re-configure and teh problem is solved, related command is as follows:
flow-action fcnc redirect ip ×.×.×.× GigabitEthernet4/1/1 vlan 156
Configuration is false. If L2 interface acts as the egress of policy route, designate VLAN number of the egress.
