I made a mistake. I changed it to 'match ip src 192.168.1.0/24' . Now it works.

I can mirror the packets (A -> B) to D. Node D forwards them to C.
Sometimes the same packets through the path A-B-C, A-D-C are not lost. Node C will receive the
same packets twice. How to handle the duplicate packet on node C ?

Maybe the duplicate packets have side effects to TCP.
