Question

In the project, which command option prevents fragmentation of oversized packets?

Answer 1

The command option that prevents fragmentation of oversized packets is DF (Don't Fragment).

Step-by-step explanation:

The command option that prevents fragmentation of oversized packets is DF (Don't Fragment). When the DF flag is set in the IP header of a packet, it instructs routers not to fragment the packet if its size exceeds the maximum payload size allowed on a network. This ensures that the packet will be either delivered in its entirety or not at all, preventing fragmentation and potential packet loss.

Here is an example of how the DF flag can be set using the 'ping' command in Windows:

1. Open the Command Prompt
2. Type 'ping destination_IP_address -f' and press Enter

The '-f' option sets the DF flag, indicating that the packet should not be fragmented.

Answer 2

To prevent fragmentation of oversized packets, the DF (Don't Fragment) bit is set to true, which prevents routers from fragmenting the packet, relying instead on Path MTU Discovery for efficient delivery.

Step-by-step explanation:

To prevent the fragmentation of oversized packets in a network project, the command option you're likely looking for is the MTU (Maximum Transmission Unit) setting, which specifies the largest packet size that can be transmitted over the network. However, specifically to avoid fragmentation, the Don't Fragment (DF) bit in the IP header of the packets can be set. When the DF bit is set to true, it instructs routers not to fragment the packet, and any packet that is too large to pass through a network segment will be dropped instead of fragmented. This strategy is often employed in conjunction with Path MTU Discovery (PMTUD) to ensure efficient and reliable packet delivery while avoiding fragmentation.
