E14.4 Host 128.138.2.4 on network 128.138.2.0/24 wants to send a packet to host 128.138.129.12 on network 128.138.129.0/24. Assume that

• Host 128.138.2.4 has a default route through 128.138.2.1.
• Host 128.138.2.4 just booted and has not sent or received any packets.
• All other machines on the network have been running for a long time.
• Router 128.138.2.1 has a direct link to 128.138.129.1, the gateway for the 128.138.129.0/24 subnet. 

 

a) List all the steps that are needed to send the packet. Show the source and destination Ethernet and IP addresses of all packets transmitted.

b) If the network were 128.138.0.0/16, would your answer change? How or why not?

c) If the 128.138.2.0 network were a /26 network instead of a /24, would your answer change? How or why not?
