You need to edit your pcap files before playing them using tcpreplay.
So for example in your pcap file there are few packets which you want to be
destined to a certain Host A's IP X.X.X.X.
You need to change the destination IP address of packets in your pcap file
and set it to IP address of Host A X.X.X.X along with that you need to
change the destination MAC address and set it to the either the MAC of next
switch or the MAC of Host A.
Make sure that you set proper Checksum at both Network and transport level.
Then play your file using tcpreplay the packets will reach to required
destination.
