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? |
