12.1

Does broadcasting increase the amount of network traffic?

12.2

Consider 50 hosts on an Ethernet: 20 running TCP/IP and 30 running some other protocol suite. How are broadcasts from one protocol suite handled by hosts running the other protocol suite?

12.3

You login to a Unix system that you've never used before and want to find the subnet-directed broadcast address for all attached interfaces that support broadcasting. How can you do this?

12.4

If we ping the broadcast address with a large packet size , as in

 sun  % ping 140.252.13.63 1472  PING 140.252.13.63: 1472 data bytes     1480 bytes from sun (140.252.13.33): icmp_seq=0. time=6. ms     1480 bytes from svr4 (140.252.13.34): icmp_seq=0. time=84. ms     1480 bytes from bsdi (140.252.13.35): icmp_seq=0. time=128. ms 

it works, but increasing the packet size by 1 byte gives us the following error:

 sun %  ping 140.252.13.63 1473  PING 140.252.13.63: 1473 data bytes     sendto: Message too long 

What's going on?

12.5

Redo Exercise 10.6 assuming the eight RIP messages are multicast instead of broadcast (assume RIP Version 2 is being used). What changes?
