There are routing in the routing table, but the router didn't forward packets correctly.
1. Check the routing table and find that the routings are correct.
2. Confirm there are no other routings which with longer mask existed in the routing table.
3. Check the fib of the slot and find that the routings haven't been loaded to the L2 Lan board.
4.Implement commands "set workmode lan-card l3centralize" under system-view. And the problem resoved.
1. The routing is wrong.
2. There are other routings with longer mask in the routing table.
3.The information in routing table haven't been loaded to fib.
Sometimes, when you use LAN board as L3 forwarding the routing table may be not correctly loaded to the board from routing table, even you find that the routing table is correct. So please pay attention to implement the commands above.
