! 1. PC 1 ping PC 2 (Capture ICMP Request and ICMP Relay)
! + Wireshark Capture
! + PC 1 : ping 192.168.10.2
! 2. Calculate Frames : |Ethernet | IP | ICMP | ICMP Payload | = ? bytes
! 3. What is MTU ?
! 4. PC1: ping 1 packet (ping -n 1 192.168.1.2)
! 5. PC1: ping with TTL = 5 (ping -i 5 192.168.1.2)
! 6. PC1: ping with ICMP Payload change to 1472
! + ping -l 1472 192.168.10.2
! + calculate frames = |Ethernet | IP | ICMP | ICMP Payload | = ? bytes
! 7. PC1: ping with ICMP Payload change to 1473
! + ping -l 1473 192.168.10.2
! + Wireshark capture : fragment packets
! 8. PC1: ping with ICMP Payload change to 1473 with DF = 1 (Don't Fragment)
! + ping -l -f 1473 192.168.10.2
! + See what will happen ? (Hit : reduce ICMP Payload to find MTU)
