Apr 7, 2024 · The upper layer protocol specified in the IP datagrams returned from routers is: c) ICMP When a router receives an IP datagram and determines that it needs to be forwarded to another network or destination, it examines the IP header to make routing decisions. Within the IP packet header, what is the value in the upper layer protocol field? Question: What is the upper layer protocol specified in the IP datagrams returned from the routers? [Note: the answers for Linux/MacOS differ from Windows here]. Normal network traffic will carry specific protocol numbers such as 1 (ICMP), 6 (TCP), or 17 (UDP). In the first part, we’ll analyze packets in a trace of IPv4 datagrams sent and received by the traceroute program (the traceroute program itself is explored in more detail in the Wireshark ICMP lab).
