hello my name is Kevin this video tutorial will walk you through the base tracer packet tracer is a very powerful

tool that allows you to emulate a network topology without physically building it with this nifty piece of

software you won't need expensive pieces of equipment or spend hours wiring things together by the time this video

tutorial is over you will know how to setup a simple network consisting of a router and two pcs configure routers

through the command line interface use simulation mode to visually trace a ping let's begin to make a simple Network

first click the routers icon in the device area at the bottom and choose the one eighth for one router move your

mouse to the logical workspace and click to place the router next click end devices in the device area choose the

generic PC and place it in the workspace repeat to add a second PC to connect them click connections and choose the

copper crossover cable click on PC 0 and click fast ethernet to connect the cable to the PCs Fast Ethernet interface then

while in control of the cable connect the other end to router zeros fastethernet 0/0 interface repeat with

PC one and the remaining Fast Ethernet interface on router 0 feel free to move the equipment around

the workspace you'll now physically set up a network in packet tracer now let's configure the network to make it work

click router 0 a window will come up go to the command-line interface or CLI tab here with this question to continue with

configuration dialog type no we will manually configure the router wood commands press return to get started as

this prompt suggests at this prompt type in able to enter privileged exec mode this is similar to route in UNIX systems

you will know you are in privileged privileged exec mode when you see the router name followed by a number sign

type in config T to enter global configuration mode type hostname router 0 to name the router next type enable

secret class to set an encrypted password for logging in to privileged exec mode in real-world situations

class is obviously not an acceptable password but for the purposes of these tutorials we will use either class or

Cisco for the password configure the password for the console line by entering line con 0 and then password

Cisco enter login to enable password prompting enter exit to return to global

configuration mode configure the password for the virtual terminal lines by entering line vty 0 space for and

then password Cisco again enter login to enable the password requirement and then exit to return to configure the Fast

Ethernet interfaces enter interface and then the interface name in this case we'll start with fast ethernet 0/0

next enter in IP address 192.168.1.1 space 255.255.255.0 to set this interfaces IP address and subnet mask

although optional you may want to add a description to the interface for later reference by entering in description

router 0 fast ethernet 0/0 last entered the command no shutdown to start the interface exit back to global config

mode repeat with fastethernet 0/1 except this time use IP address 192.168.1.1 for the IP address and for

the description you can use router 0 FASS Ethernet 0 / 1 and don't forget to type in no shutdown to enable the

interface exit out of interface config and then exit out of global config mode hit enter this prompt and you will be

back at privileged exec mode enter in show running - config to display the current configuration continuously hit

enter to scroll down you will see all the configurations you just set to save this configuration to the NVRAM

so that when the router boots up it automatically loads it enter in copy running - big space startup - config hit

enter this prompt to confirm router configuration is now complete close the router zero window to configure the PCs

first click PC 0 go to the desktop tab here click IP configuration we will set a static IP set the IP address to

192.168.1.2 then hit tab keep the default subnet mask hit tab again and enter 192.168.1.1 for the default

gateway close the pc 0 window repeat with pc 1 except for the IP address use 192.168.20.10 dot 2.1 and then close pc

ones window by now there should be green dots on the cables near devices this means that they

are connected let's try pinging PC one from PC 0 click PC 0 go to the desktop tab and click command prompt this acts

just like a DOS prompt in a Windows operating system for example you can type in ipconfig and you can see the

details of the IP address subnet mask and default gateway enter the command ping 192.168.20.10

let's visually see the pane with simulation mode near the bottom right corner you will see a tab with a clock

labeled real time click the tab behind it to activate simulation mode here click Edit filters click the show all /

none box once to clear the selections check off ICMP and click out of that on the right sidebar click the first yellow

envelope with a plus this one this will allow us to choose a source and destination for our PD u or protocol

data unit click PC 0 and then click PC 1 an envelope with a randomly assigned color will appear at PC 0 in this case

it's green click Auto capture / play to begin the paying simulation observe as the PDU travels to router 0 and then to

pc 1 and then back once it returns back to PC zero the PDU is verified and checked off which means

the ping was a success done you have now successfully completed this packet tracer tutorial thanks for watching
