Note there is no host with this IP address in the current configuration of the lab network. Save the tepdump output of the first few packets for the lab report. After getting the necessary output, terminate the telnet session. From the saved tepdump output, describe how the ARP timeout and retransmission were performed. How many attemps were made to resolve a non- existing IP address? 8 3. Explain briefly the purposes of the following tepdump expressions. a. tepdump udp port $20 b. tepdump -x -s 120 ip proto 89 c. tepdump-x-s 70 host ip addrI and (ip addr2 or ip addr3) d. topdump -x -s 70 host ip addrl and not ip addr2 4. Set up a simple wired network with two nodes nO and nl for UDP CBR traffic. Provide duplex link between these nodes having propagation delay of 10msec and capacity of 10Mb by considering no as source node and nl as sink node. IL ADDITIONAL EXERCISES: I. Set up a simple wired network with two nodes nO and nl for TCP FTP traffic. Provide duplex link between these nodes having propagation delay of 10msec and capacity of 10Mb by considering no as source node and nl as sink node
