7.6.1 Packet Tracer - WAN Concepts

one concepts investigate consumer one technologies for home and mobile devices explore consumer one technologies look at the two home networks yellow square is the consumer one technologies consumer one technologies and there are two home networks this using home cable network and this is another home dslr network the the ping section what are the one the technologies in use the first home network using cable and the second home network using dsl cable and dsr examine the connections used in the network topology by selecting the connections icon what media is used to connect the two home networks to the isp okay go to connections down here connections and look at this this this cable is this this blue cable is coaxial and this another cable is this phone cable coaxial for cable network and phone cable for dsl network the coaxial cable for cable and phone cable for dsl what devices in the home networks are directly connected to the isp this is the isp and for home cable the device is coaxial splitter and for dslr the device is the dsl modem click the dsl modem and open the physical tab click here physical what ports are available on the device and what is connected to them okay assuming dsl model has two ports one is connected one port is connected to isp to telco this this port line zero connected to isp telco and another port is connected to the wireless router is this faster net port what is the purpose of the dsl model it converts the telephone data and network signals to ethernet for the home network what is the type of connection between isp telco cable company network in the home cable network okay this is isp telco and this is the home cable network the type of connection is made with coaxial cable coaxial cable why is the splitter necessary okay this is the splitter before the coaxial cable goes to cable modem there is a connection splitter the splitter is necessary because the cable car is about digital data and video signals the splitter splits the media so that the data signal can be sent to the cable model and the video signal to the tv you got the ports on the cable modem click here cable modem what does the cable model do the cable modem converts the cable data signals to ethernet signals what connections do it have it is connected to coaxial cable from the splitter and udp cable from the ethernet interface okay coaxial cable to the splitter using this port coaxial and qdb cable connected to wireless router on this port first ethernet zero which port does the cable from the cable model connect to on the home wireless router okay go to wireless router click here okay the connection to cable modem is using the internet interface this blue blue ethernet connector where did the interface ip address come from okay go to graphical user interface and go to status and now you can see internet connection automatic configuration dhcp okay so the dhcp server is isp and wireless router will get the ip address on internet interface using dhcp look at the smartphone this smartphone on on the street what is the ib address click here on smartphone text desktop command prompt ipconfig to verify the ip address okay and this is the wireless for wi-fi it does not have ip others with the 3g 4g cell connection 198 51 100 101 okay also you can see this on 3g 4g cell is configured with with dhcp and using this ips 1ia 51 100 101 where did the ip address come from okay if this smartphone is using the hcp the ip address come from isp telco isp telco is the dhcp server what data service is in the cell phone currently using okay click on a smartphone okay 3g 4g network 3d 4g network explore the business one okay this is the business one this light blue square you got the connections what different types of connections do you see in use in the business network first this black black cable is copper straight through this is for ethernet another is this red [Music] this red is fiber okay here is orange with bit okay here is orange but when you place on the topology is now red is fiber fiber optic fiber optics cable and this another is this serial cable open the physical view for the store not switch okay this is store net click here physical tab what types of interfaces are present this switch has gigabit interfaces okay on this side using fiber optics but on this another side using a copper or ethernet cable okay these are the copper interfaces the ethernet interfaces and this another the fiber optics interfaces okay copper with ethernet and fiber optics on this another side also using ethernet but fiber optics okay this is the the name glc lhsmd is this glc lh smd gigabit base gigabit ethernet port for spf okay for fiverr connection which interface and media are used to connect the store networks to the business headquarters network okay these are the stores and these are headquarters okay stores store one stores 2 and store 3 are connected to a store net store net switch and using fiber optic fiber optic cable and store nut is using copper ethernet cable to business headquarters why was this done this was done because of the distance required to reach the stores in real world another provider would provide this fiber optic service is using fiber optics to connect the headquarters and store and stores what type of one service is used to connect the business headquarters router to the isp okay the business headquarters router is connected to isp telco and the router is using a serial connection to connect the isp explore connectivity big devices within the business one and the consumer one networks also pick between the networks and the web server okay first pink devices within the business one okay for example go to store one one and ping this and pink server zero server zero ip addresses 18168 101 100 182 161 92 168 101 100 success and okay and from store one one pick the server pick the server 20165 200 to 226 ping 209 165 200 to 226 success from a smartphone and go to a smartphone and common prompt for example pink laptop one laptop one ips 192 168 0 100 p182 168 0 100. okay being fails because wireless router is using and not and when you are using that you cannot ping a device in the internal network okay go to smartphone and ping the server this web server so on i165 200 to 226 165 226 success okay and don't forget between the networks and being for a smartphone being server zero and server zero api is 192.168.101.100. 192.168.101 100. okay pin fails con can our house ping each other and the web server okay within business one devices can ping each other from business one is possible to ping web server we think a consumer network being is not possible because where left routers are using not but from consumer network is possible to pin web server and finally it's not possible being from consumer one to business one and also will not be possible being from business one to consumer one for uh security reasons and for the not used on wireless routers is this a good situation yes these networks should not be directly reachable from outside for security reasons thank you very much you
