Investigate Unicast, Broadcast, And Multicast Traffic Instructions

PPacket Tracer T - Investig gate Unicast, Brroadcas st, and M Multicastt T Traffic T Topology O Objectives Part 1: Ge enerate Unic cast Traffic Part 2: Ge enerate Broa adcast Traffic Part 3: Investigate Mu ulticast Trafffic B Backgroun nd/Scenario o This activity will examin ne unicast, brroadcast, and d multicast be ehavior. Most traffic in a ne etwork is unica ast. When a PC send ds an ICMP echo e request to a remote ro outer, the sou urce address in the IP paccket header iss the IP address of o the sending g PC. The des stination addrress in the IP packet heade er is the IP ad ddress of the interface on the rem mote router. The T packet is sent only to the t intended d destination. Using the ping comma and or the Add d Complex PDU feature off Packet Traccer, you can d directly ping b broadcast addresses s to view broa adcast traffic. For multic cast traffic, yo ou will view EIGRP traffic. EIGRP E is use ed by Cisco ro outers to exch hange routing g informatio on between ro outers. Routerrs using EIGR RP send packkets to multica ast address 2 224.0.0.10, wh hich represents the group of o EIGRP routters. Although h these packe ets are receive ed by other d devices, they a are dropped at a Layer 3 by all devices ex xcept EIGRP routers, with no other proccessing requiired. P Part 1: Generate G Unicast Traffic T S Step 1: Use ping to ge enerate trafffic. a. Click PC1 and click k the Desktop tab > Comm mand Promp pt. b. Enter the ping 10.0.3.2 command. The ping should succe eed. S Step 2: Enter Simulation mode. a. Click the Simulatio on tab to ente er Simulation mode. a verify that only ICMP and a EIGRP evvents are sele ected. b.

Examine the Layer 3 information for all of the events. which is the IP broadcast address you configured when you created the complex PDU. b. Notice that the destination IP address is 255. It also appears in the PDU List window. the default for Select Application: is PING. The PDU Information window opens. b. Step 3: Examine unicast traffic.Investigate Unicast. This packet is sent to the switch and then broadcasted to PC2. c. the last column contains a colored box that provides access to detailed information about an event.

It is the first PDU for Scenario 0. what changes occur in the Layer 3 information of the Out Layers column at Router1. The PDU at PC1 is an ICMP echo request intended for the serial interface on Router3. The icon for this is in the right toolbar and shows an open envelope. Which devices did the packet travel through with the unicast transmission? Od PC1 do SWITCH1 do RUTER1 i nazad. FTP. HTTP. POP3. © 2013 Cisco and/or its affiliates. HTTPS. FINGER. SFTP. Analyzing the OSI Model information. PC3.2 command. TFTP i ostali. What are at least 3 other applications available for use? DNS. Examine the Layer 3 information for all of the events. Click Reset Simulation. Click Capture/Forward twice. Click Capture/Forward repeatedly and watch while the echo request is sent to Router3 and the echo reply is sent back to PC1. What two changes take place at Layer 3 when the packet arrives at Router3? Odredišna i izvorišna IP su zamjenjene i ICMP poruka je 0. Stop when the first echo reply reaches PC1. Click PC1 to serve as the source for this test message and the Create Complex PDU dialog window opens.0. Enter the following values:  Destination IP Address: 255. SSH. What layer does this transmission start at and why? Sloj 3 koji je zadužen s IP i ICMP. Click Create PDU. Part 2: Generate Broadcast Traffic Step 1: Add a complex PDU. SMTP. Notice that both the source and destination IP addresses are unicast addresses that refer to PC1 and the serial interface on Router3. PING. Click the colored box in the last column for the first event. SNMP. After you are done examining the broadcast behavior. The switch will forward the packets to the PCs. Click Capture/Forward until you see the EIGRP packet arrive at the PCs. Click Capture/Forward.Investigate Unicast. Part 3: Investigate Multicast Traffic Step 1: Examine the traffic generated by routing protocols. What do the hosts do with the packets? Host odbija pakete.0. ali ga obrade samo uređaji koji su dio multicast grupe. and Multicast Traffic f. g. Click Capture/Forward again. What happens to those packets? Paketi su ispušteni i ni jedan dodatni proces nije obavljen. c. d. because they are part of the multicast group. This document is Cisco Public. What is the destination address of each of the packets? 224. Ne mora jedino ako je ruter postavljen na forward. Examine the Layer 3 and Layer 4 information for all of the EIGRP events. Click one of the packets delivered to one of the PCs.10 . Multicast šalje paket svim računalima u mreži. Page 3 of 4 .to je multicast IP adresa za EIGRP protokol.Packet Tracer . The routers accept and process the packets. delete the test packet by clicking Delete below Scenario 0. © 2013 Cisco and/or its affiliates. Does the broadcast PDU ever forward on to Router2 or Router3? Why? Ne. a. All rights reserved. Broadcast šalje svim računalima u mreži.0. The packets are sent to the two other routers and the switch. Examine the contents of these packets by opening the PDU Information window and click Capture/Forward again. Broadcast. b. Brooadcast treba ostati uz lokalnu mrežu. what are the major differences in delivery? Unicast paket putuje kroz mrežu i namijenjen je jednom računalu. Based on the traffic generated by the three types of IP packets. EIGRP packets are at Router1 waiting to be multicast out of each interface.
