1.6.2 Packet Tracer - Configure Basic Router Settings - Physical Mode

this is a comprehensive packet razor physical mode activity to review previously covered ios router commands you will cable the equipment and complete basic configurations and interface settings on the router set up the topology and initialize devices cable the network as shown in the topology drag the cisco 43 21 isr integrated services router and okay this is this is the router for 4321 okay the cisco 2960 switch this is the the switch cisco 3960 and the server the server okay from the shelf to the rack okay to the rack not on the table drag pc from sheriff to the table pc down here and drag to the table on the left side on the table cable the devices as specified in the topology diagram use copper stray through cables okay from gigabit zero zero zero on router to the server use a copper straight through cable okay but copper straight through cable from gigabit zero zero on the router gigabit zero zero zero on the router to the server to this fast internet interface from gigabit tier one under router to faster not five on the switch straight through copper cable and from gigabit zero zero on the router to faster.net 5 on the switch and from faster at 6 on the switch to pc the same cable from 406 to fast internet on the pc from pc connect a console cable to the cisco 4321 isr okay and now use the console connection from the pc from rs to 3d to port from pc to console port on the router now you have this connection console connection power on the cisco 4321 pca and server okay click here to power on the router now you can see the green indicator power on the the server okay now you can see this indicator and power on the pc the 2960 switch should power on automatically the 2960 switch doesn't have a power bottom so this connection to the power distribution device is enough so the switch is power on and for fewer devices symbolic high connectivity configure pc interfaces configure ipl subnet masks and the full gateway on pci api as soon as mask default gateway on server and use the addressing table to configure this for pca and this for the server okay this is for pci ipv4 and ipv6 so click on pc desktop ip use static to configure 180 168 110 prefix 24 is 250 by the way twice by zero the photographer 180 168 one one ipv6 with static 2001 dba acad 1 column column 10 prefix 64. default gateway fea 0 colon colon one okay look at this two zero zero one dba acd one column column tank profit sixty four the four gateway fe h zero power column one okay this okay very good and click on the server desktop ip configuration static for ipv4 and configure this 182 168 zero tank prefix uh 24 forget 182 168 01 ipv6 use static 2001 dba hcad column column tag prefix 64. default gateway f3h0 clock log one okay be careful and that's it and configure the router console into the router and enable privilege excel mode okay remember i have the console connection to the router from pc so click on pc and go to terminal okay okay enter would you like to enter initial configuration dialog no and the rather enable privilege exec mode enabled now you are on privilege access mode under configuration mode configure terminal your global configuration mode assign a device name to the router use their name on the addressing table r1 host name one set the router's domain name ccna dashlab.com the main dash name ccna dashlab.com enter encrypt the plain text passwords service password configure the system to require minimum 12 character password security password mean length configure the username ssh admin with an encrypted password of 55h adm exclamation and 2020 okay case sensitive a username call it ssh admin case sensitive encrypted password use secret and the password is 5 5 h adm exclamation and 2020 okay case sensitive enter generate a set of crypto keys with uh 1034-bit modules crypto key generate rsa in general case modulus 1034 enter okay very good assign dollar cisco exclamation asterisk as the privilege exit password okay this is the enabled secret hang case sensitive password dollar cisco exclamation pride and asterisk okay case sensitive be careful enter assign dollar cisco exclamation exclamation com asterisk is the console password line console console zero password dollar cisco exclamation exclamation call asterisk enter configure sessions to disconnect after four minutes of inactivity and enable logging exact dash timeout four minutes zero seconds enter and enable enable login don't forget that login enter exit assign dollar cisco exclamation exclamation pty asterix the bty password okay nine bty 0 to 15 i will use all bty lines enter and the password will be dollar cisco exclamation exclamation bty case sensitive and asterisk ok enter configure the vty lines to accept ssh connections only transport input ssh configure sessions to disconnect after four minutes of inactivity next time by forming zero sequence enable logging using the local database so use login local enter to use this user name this local username and password okay then exit create a banner that warns anyone accessing the device that when authorized access is prohibited okay a banner banner message of the day use on how to rise access is prohibited and enable ipv6 routing ipv6 unicast dash routing configure all three interfaces on the router with the ipv4 and ipv6 addressing information from the addressing table above configure all in three interfaces with descriptions activate all three interfaces okay so configure these three interfaces on the router okay these interfaces are gigabit zero zero zero you go with zero zero one and look back and if i go with zero and set the description don't forget that it's only a label you can use any description so for example for you with 0 you can say connection to server connection to server connection server and ip address ipv4 others i use this all this ipv4 and ip6 0 192.168.01 24 is divided by divided by 250 under ipv6 others 0 0 1 dba acid colon column one and prefix 64. okay be careful enter and ipv6 address the link local address fva0 column one specify is link dash local enter and enable the interface don't forget that no shutdown enter very good now configure gigabit 001 okay this is the another side so the description may vary the connection to the to switch as well the ip address is guanguang 181 6811 prefix 24 ipv6 address 2001 dba acad column 1 column column 1 prefix 64 enter the same link local address enter enable the interface not shut down okay and please don't forget the loopbox hero with these configurations interface loop back 0 enter the description can be in description look back ip address 1001 fixed 24 to 50 by 285 to 850 ibv6 address is 2001 dba acad two column column one prefix 64 the same link local address enter okay and the interface is already up because it's a virtual interface you don't you don't need the not shutdown commands okay and exit and now the router should not allow bty logins for two minutes if three failed logging attempts occur within 60 seconds okay use this command login space block dash for and two minutes is 120 seconds if three five let logging attempts occur then three if three failed logging times occur within 60 seconds within 60 seconds and now set the clock on the router clock set request some help using the question mark okay unrecognized command because this should be done on privilege access mode and you are on and i am on global configuration mode so exit cloud set question mark hour minute second hour 12 37 okay and zero zero question mark the day of the month is nine question mark the month september the year 2021 enter very good save the running configuration to the sram configuration file copy running touch config to startup dash config enter enter okay what would be the result of reloading the router prior to completing the copy running config storage config command okay you will lost all your configurations the contents of the running configuration in ram would be erased during reloads as the result the router would boot up without a startup configuration and the user would be asked if he would like to enter initial configuration dialog verify network connectivity using the command line at pci ping ipv4 and ipv6 addresses for the server okay go to pc and close terminal open command prompt and ping the ipv4 and ipv6 addresses on the server i think 192.168.010. success pink two zero zero one dba ac column column 10 and success required being successful yes from pca remotely access r1 using telnet ssh client using the internet ssh client on pci open an ssh session to the r1 loopback interface ipv4 others okay and close command prompt open the internet ssh client and select ssh okay because say ssh session to the loopback the loopback of the router is this and ip address 1001 ensure that the connection type is set to ssh and use ssh admin as the user name remember the user configured on the router is ssh admin case sensitive connect now the password is this remember this password okay be careful five five h adm exclamation and 2020 enter okay now you are on the router with the remote access successful yes using the telnet ssh client on pca open ssh session to the r1 loopback interface ipv6 address ensure that the connection type is set to ssh use the ssh admin as the username and the password okay now the same the same process would use ib6 okay exit from the from the router okay the current session has classed do you want to establish a new session with the previous session options now and ssh the ipv6 look back remember this 01 dba hcid 2 column column and the user username is ssh admin connect okay enter try again no so i will use another method use command prompt you can use ssh option l is not one is l the username is ssh admin use the ipv6 of blue box hero use this the first t001 dba aca acad column two column column one enter connection timeout okay this is not a configuration issue this is not a configuration error or problem this is a packet razor issue okay so i can reload the router you can go to terminal okay and apply the reload command and remember that you entered the command copy running config to serve config to save the changes on this router so you can reload the router with reload commands without losing the configurations or you can or or also you can reload pressing the power on boot on power off and then power on okay this is another way to reload the router click on the pc you are on the terminal the console connection wait a moment okay and close terminal open the telnet ssh client the host name the loopback ipv6 address 2001 dba hcad hcad column two column column one and the user name ssh admin case sensitive okay and connect now the password is remember 5 h abm exclamation and 2020 enter okay very nice okay you are on r1 with the remote access successful yes why is the telnet protocol considered to be a security risk the telnet session can be seen in plain text it is not encrypted passwords can easily be seen using a pocket sniffer okay and okay do not exit from r1 okay enter you are on r1 and display the router information you will use show commands from ssh session to retrieve information from the router establish an ssh session okay use the choose telnet ssh client on pca use the loopback interface ipv6 address use the username and password okay okay this procedure already done retrieve important hardware and software information use show version show version space okay remember i am on user accent mode but show version is working very well on user access mode okay again show version [Music] space space space okay and what is the name of the ios image that the router is running up here this is the the name ios image isr 4300 does universal k9.03.16.05 that s that 115-3 that is 5 that exed that spi that being gavin is an extension how much non-volatile random access memory heavy ram does the router have okay non-volatile configuration memory is this 32 768 kilobytes okay this is this is about 32 megabytes okay how much flash memory does the router have a flash memory this number okay about 3 million kilobytes of flash memory and this is about [Music] three gigabytes okay about three gigabytes show commands often provide multiple screens of outputs filtering the output lets you display certain sections of the output to enable the filtering command enter a pipe a pipe character after a show command follow it by a filtering parameter and a filtering expression you can match the output of the figuring statement by using the include keyword to display all lines from the output that contain the filtering expression filter the show version command using show version pipe include register to answer the following question what would be the good process for the router on the next reload if the configuration register was hexadecimal number two one four two okay the current session has clustered do you want to restoration new session with the previous session options yes okay and remember the password is possible okay it's a nightmare but this is the password okay five five h adm exclamation and 2020 enter okay again five five h adm exclamation and 2020 okay very good show version again but use the pipe and include the keyword register okay enter and look at this configuration register is hexadecimal number two one zero two okay okay is a filter if you will use only show version space space this is the line that you filter it okay the keyword to register is included on this line so that's why you will see only that line when you apply the filter okay so the answer is okay what what would be the pro the boot process for the router on the next reload if the configuration register was hexadecimal number two one four two okay this and this is uh two one zero two this is normal register normal boot but what happen if you will change this to hexadecimal to 142. in most cases the configuration register will have a value of hexadecimal to one co2 signifying that the router will undergo a normal boot load the ios from the flash memory and load the startup configuration from the mbram if present if the config register is hexadecimal number 2142 the router will bypass the startup config and begin at the user mode command prompt if the initial boot fails the router goes into wrong monitor mode okay wrong mode display the startup configuration show a startup config and you need to access privilegex mode use the enable command and remember the password was this the enable password dollar cisco exclamation prime asterisk dollar cisco exclamation prive asterisk okay sensitive very nice you are on privilege excel mode and do the following show startup config show start up dash config enter space space space space space okay and how are passwords presented in the output okay passwords are encrypted passwords are encrypted because of the service password encryption command okay passwords are encrypted okay this uh this password and this another password will be encrypted also if you will not use the service password encryption command because both are using the secret the secret keyword that will encrypt the password anyway show running config and pipe section bty okay show running dash config use pipe and you will filter to only show the section of vty lines okay and now you will see only bty configurations okay this part remember that you will see only those lines what is the result of using this command this is the result okay a user receives the running config configuration output beginning with the line that includes the first instance of the filtering expression display the routing table show ip roots what code is using in the routing table to indicate the directly connected network a c for directly connected network okay one two three three directly connect the networks and how many road entries are coded with a c codes okay three display a summary list of the interfaces show ip interface brief show ip interface brief enter what command changed the status of gigabit ethernet ports from administratively down to up okay gigabit ports are up loopback interface up up state status up and protocol app and what command changed the status of the gigabit ethernet ports from administratively down to up the command is not shut down use show ipv6 interface brief the same command with this ipv6 show ipv6 interface brief what is the meaning of the upper part of the output okay for example gigabit zero zero zero state up protocol up up status reflects the layer 1 and layer 2 status of the interface and does not rely on layer 3 for status on server change its configuration so that it no longer has a static ipv6 address then issue the ipconfig command on the server to examine the ipv6 configuration ok click on the server the server is here click here go to desktop ip configuration okay this is the ipv6 configuration and it's static change this to automatic and look at this you'll save it ipv6 address automatically from router r1 okay this is the slack configuration okay the stateless address auto configuration a slack okay and ipconfig on the same server comma prompt i pick config what is the ipv6 address assign it to the server this is the ipv6 address very good what is the default gateway this is the link local address of the interface on the router from pcb issuer pink to r1 default gateway link local address okay click on on the pc click close terminal okay close the ssh client go to comma prompt and ping the [Music] link local ladders of yugabit001 this feat zero column column one fe h0 column one success because the was the ping successful yes yes from server issue appears to the r1 ipv6 unicast address two zero zero one dba academy one okay click on the server and ping to this ip address the ip address of gigabit zero zero zero router r1 right click on the server 2001 dba pcid column column 1 success was it successful yes absolutely in researching a network connectivity issue a technician suspects that an interface was not enabled what show command could the technician use to troubleshoot this issue the technician can use show ip interface brief show interfaces or show a startup config to provide the information in researching a network connectivity issue a technician suspects that an interface was assigned an incorrect subnet mask what show command could the technician use to tribute this issue the technician can use show a startup config show running config show interfaces show protocols okay completion 95 percent change the ip address on the server 201 dba hcad [Music] tank pcid column column time prefix 64. forget eight zero column column one okay this is this default gateway okay close you know completion one hundred percent very good thank you very much you
