So, the switch just passes the frame, instead of to generate a new frame?
So, the router just extracts an incoming frame and generate a new frame to output?
Because the router extracts the incoming frame and generate a new frame, the source and the destined MAC must changed. However, the source and destination IP addresses in the datagram never changes, except during the NAT/PAT process?
Am I correct?
