1. Ping www.google.ca- You receive the IP address.

- You also get the information on Ping Statistics, such as packets send, packets received, packets lost, and Approximate round-trip time.

2. Type ping www.kpu.ca -f -l 1500

- the display, packet needs to be fragmented but DF set, means that the frame is too large to be on the network and needs to be fragmented. Because we used -f switch with is ping command, the packet was not sent, and the ping command returned this error.

3. Type ping www.kpu.ca -f -l 1300

- You can see that the max. packet size is less than 1500 bytes and more than 1300 bytes.

4. Try different values Until you find the max. frame size.
5. Type ping www.kpu.ca -f -l 1373
6. Type www.kpu.ca -i 3.

- TTL expires in transit means that the router discarded the frames because its TTL has expires.

7. Type ping www.kpu.ca -i 1 -n 1
8. Type ping www.kpu.ca -i 2 -n 1
9. Type ping www.kpu.ca -i 3 -n 1
10. Type ping www.kpu.ca -i 4 -n 1
11. Type ping www.kpu.ca -i 10 -n 1

- Repeat the previous step until you reach the IP address for www.kpu.ca
