is it necessary to modify the topology during tcpreplay

[lululouisa]

Becasue of fixed interface during the tcpreplay, should i modfify the ip address of host to match the pcap.file packets?
For example, in pcap.file there are some malware packets whose srcip is 175.45.176.0. However, when i makerun in mininet, the host1 ip address maybe initialized to 10.0.1.1. When i tcpreplay intf1=h1-eth0, is it ok without changing the h1 ip address?

Thank you~~~

Hello,
Yes normally it should work without the need to change the IP address. In case some problem is there then I can see more in detail.
