Serial initial routing

hi friends welcome to all in this video we are going to discuss CCNA version 7 packet tracer activity configure initial router settings before coming to this activity friends if you are watching our channel first time or if you like to get this type of technical videos in future considered subscribing also don't forget to enable that Bell icon near to the subscribe button so that you will get notification message whenever we upload a new video also if you like to get a more technical contents you can visit our website link given in the description now coming back to our packet tracer activity configure initial router settings here we can see the objectives in part 1 we will verify the default router configuration then in part 2 we will configure and verify the initial router configuration and then finally we will say with our running configuration file in this activity we will perform basic router configuration tasks we will secure access to the CLI and the console port are using encrypted and plaintext passwords we will also configure messages for users who are logging in to the router this banners 1 and authorize the users that access is prohibited finally we will verify and save our running configuration ok firstly coming to part 1 verify the default or router configuration so in step 1 establish a console connection to r1 so coming to a topology here we can see our router r1 and our n2 device PC a pure choose a console cable from the available connections so coming to our packet tracer left corner here we can see connections we will click on these connections and here we can see console we will click on this console then we have to click BCA then we have to select this rs-232 then the other end we have to connect to the router r1 click r1 and the select console ok so coming to our PC a and B here we can see rs-232 we will connect to this rs-232 the other end or an r1 here we can see console we will connect to console yes once we connect these devices are using console cable here we can see our completion status it's now 20 percentage okay next we have to click PC a then they have to go to this a desktop tab then terminal ok that click OK and press Enter you are now able to configure r1 we will check that we will go to PC a and here we can see the number of tabs physical config desktop programming attributes we will click on this desktop tab and here we can see terminal sure we can see port configuration we will leave this port configuration as a default then we will press ok pure now it shows / so return to get started so we will press ENTER yes now we accessed our router r1 I using this set terminal so now we will be able to configure this device what is next coming to step 2 enter privileged mode and examine the current configuration you can access all the outer commands from privileged exit mode however because many of the privileged commands configure operating parameters privilege the access should be password protected to prevent unauthorized use yes that's correct so enter privileged x ik mode by entering enable command yes we can do that we are going to give enable then press enter no we are in privileged exit mode notice that the prompt changed in the configuration to reflect privileged exit mark as we have seen that so this prom the router greater than now changed to router hash now enter the show running - config command like this okay in the privileged x ik mode we can do that too here we will give a show running - config in presenter we have some kishan's here what is the routers hostname so here we can see hostname it's a router the default a name ok how many fast ethernet interfaces are does the router how ok here we have more information so we can press ENTER or space will press a space ok and here we can see Gigabit Ethernet Gigabit Ethernet we will let scroll down so that we can see faster current here we can see faster permit 0 / 1 / 0 first authority 0 / 1 / 1 faster at 0 / 1 / 2 and the first parent 0 / 1 / 3 so total we have 4 faster third interfaces know how many Gigabit Ethernet interfaces at does the router how okay here we have seen that a Gigabit Ethernet sure we can see Gigabit Ethernet 0 / 0 and a Gigabit Ethernet 0 / 1 so in this router we have two gigabit ethernet interfaces next is how many serial interfaces does the router have okay here we can see CDL 0 / 0 / 0 and the serial 0 / 0 / 1 so in this router we can see two serial interfaces next is what is the range of values shown for the vty lines ok we'll scroll down and here we can see line vty it's from 0 to 4 next is to display the current contents of env ROM we have to give this show command show startup - config so it will show this message startup config is not present ok we will check that show startup - config and we'll press enter and here we can see it shows startup - config is not present why does the router or respond with the startup config is not present message obviously because there is no content in NVRAM whenever we do some configurations those configurations are saved in ROM and if we know that rami say a volatile memory so a when power goes or when we restart our device all the content from the RAM will be erased for that what we have to do we have to save the content from Ram to NVRAM so once we copy the content from Ram to NVRAM we can see the content of this Ashok Amanda shows up - config yes in the last part we will see how to save from ram through NB era now we will come to party to configure and verify the initial router configuration to configure parameters on a router you may be required to between various configuration modes notice how the prompted changes as you navigate through the iOS configuration modes yes coming to step on configure the initial settings on r1 they're given a note here if you have difficulty remembering the commands refer to the contents for this topic the commands are the same as you configured on a switch in one of the previous video we have seen the initial configuration of a switch sure we are going to use those same commands so what we used for the initial switch configuration and it's correct symbol we will see that configure r1 as the hostname we can do that we have to go to global configuration mode now we are in privileged exit mode here we have to give a configure then we can press ENTER or we can give it terminal also now we have to set the hostname we have hostname then we have to specify the name as specified its r1 then press Enter and here we can see now the hostname is changed from a router to r1 now configure message of the day text that is motd banner and authorized access is strictly prohibited okay we will copy the text and coming to our router here we are going to set the banner motd then we have to start with any delimiter okay here we will use double quote then our message we already copied that and authorized the access is strictly prohibited then we will end it with the same delimiter double quote would be used then press Enter now higher crypt old plaintext passwords use the following passwords okay we have to encrypt all plaintext passwords also we have to set these following passwords privilege the x''k it's unencrypted we have to use the as cisco then privilege the x''k encrypted password we have to give it's a secret then we have to configure console password as I let me in first of all we will configure a privileged Xing password plaintext password we have to give us a Cisco ok we can give that in global configuration mode here we have to give enable we have a password then we have to specify the password is it's a Cisco then press enter next we have to configure encrypted privileged exit password we have to set the password as it's a secret ok so be able to give the command is enable a secret then we have to give or a password it's a secret now we will configure console password as I let me in so we have to go to line console line console slot 0 ok and press enter password it's a let me in you will give that here let me in then we have to give a login command now we will encrypt all plaintext passwords using the command service password - encryption and press enter next we will go to step 2 verify the initial settings on our one verify the initial settings by viewing the configuration for our one what command do you use obviously we have to use a show running config command to verify the initial settings we can give that we have to go to privileged exit mode either by exit command or we can give a control Z shortcut key press Enter ok here we are going to give a show or running config press enter here we can see hostname is r1 and enable secret we can see encrypted password enable password this is also encrypted because we given a service password encryption ok here we can see line console 0 and the password it's encrypted and here we can see our banner motd and authorize it access is strictly prohibited and here in this banner motd we can see some characters in the beginning and at the end these are the delimiters this delimiters will not be displayed in the message ok now let's see to the current console session until you see the following message our one CI and zero is now available press return to get started ok we can do that just we are going to exit from the current console session so here we can give exit then press enter here it shows so press return to get started we will let press enter press enter you should see the following message ok we will press enter sure we can see these messages and authorized access is strictly prohibited this is the message what we said I mean the banner motd then it will prompt for the user access verification so here we can see that same thing here our banner motd and its profit for the password no a why should every router have a message of that day that is motd banner yeah it's just a message to the intruders we are giving a warning anyone like unauthorized access is strictly prohibited if you are not prompted for a password before reaching the user exit from what console line command did you forget to configure here for us it's prompted for the password suppose if it is not prominent for the password you may be from forgot to give in command which we already given in the console line Nexus enter the passwords and I so sorry to return to privileged exit more okay so here we'll press ENTER and it's a problem for the password password isa let me in okay we are in a user X Sigma now we will go to privileged x''k mod enable and press enter so again it's prom it for the password actually we said to password here for the privilege at X Sigma one is a unencrypted password it Cisco then encrypted password it's a secret first we will try this Cisco know it's not accepted now we will try this encrypted password it's a secret here we can see it's working next is why would the enable secret password allow access to the privileged x ik mode and the enable password no longer be valid yes here we configured both enable secret and enable password and if you said these two password enable a secret password will override the enable password hence to go to this privileged x ik mode from user X ignored we have to use enable secret password next user if you configure any more passwords on the router are they displayed in the configuration file as a plain text or in encrypted form explained yeah once you give that service password encryption all the plaintext password will be encrypted also water password we are going to set in future also will be encryption okay now we are going to part 3 save the running configuration file step oven save the configuration file to envira you have configure the initial settings for our burn no back up the running configuration file to NVRAM to ensure that the changes made are not lost if the system is rebooted or loses the power what command did you enter to save the configuration to NVRAM what is the shortest and ambiguous version of this command ok we will check that so to say from Ram to nbrm we have to use this command copy running-config space startup config and the destination file name ok we will give this startup config the default name so just press Enter building configuration ok it's copied next - so what is the shortest and ambiguous version of this command we will see that we will try with the sea or then we will put question mark we can see three commands with the sea or but you to see ope how only one command it's copy then we will give a space for running config we will give our then question mark ok we have only running config then we will give space for startup config we will try yes with a yes we have two commands so we will give st ok it's a startup config so here we can see the shortest version of this command COP space our space st then we can press enter the station file name again we can press Enter ok now we will go to step two optional say with a startup configuration file to flash although we will be learning more about managing the flash storage in a router in later chapters we may be interested to know that as an added backup procedure we can save our startup configuration file to flash also by default to the router still loads the startup configuration from NB Ron but if NVRAM becomes corrupt we can restore the startup configuration by copying it over from flash no complete the following steps to save the startup configuration to flash examine the contents of flash using this show flash command we have to give like this show flash it's a cho w show flash know how many files are currently stored in flash one two three here we can see three files which of these files of would you guess is the iOS image here we can see one iOS image okay what do you think this file is the iOS image because here we can see the extension of this file user dot bin also we can see track error more space we'd use the more memory space next is a copy start up - config space flash so we are going to copy the content of a startup config to flash destination file name we can give a default file name okay here we'll give that copy start up - config space flash press enter destination file name default ok the router prompts you to store the file in flash using the name in brackets if the answer is yes just press Enter if not a type an appropriate name and press Enter ok here we given this a default name just to be pressed to enter use the show flash command to verify the startup configuration file is now stored in flash ok we will see that using this show commander show flash and here we can see our fourth defile startup-config this is what be configured from standard config to this flash ok that's all in this packet tracer activity configure initial router settings here we can see our completion status it's a hundred percentage No dear friends if you have any doubt any suggestions please comment below also if you liked our video give a thumb and share with all your friends also if you like to get more technical contents or if you like to contact our team you can visit our website a link I given in the description so stay tuned and we will meet again in the next video thank you
