7.2.10 Packet Tracer - Configure DHCPv4

hi friends welcome to world in this video we are going to discuss CCNA version 7 packet tracer activity configure DHCP version for people coming to this activity first if you like to get any CCNA online classes or any other technical support you can contact our team using our website link you will get from the description below and also if you like to get at these 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 now coming back to our activity sure we can see our addressing table and coming to the objectives in part 1 configure a rotor set DHCP server then configure DHCP relay then configure a router as a DHCP client and finally verified DHCP and connectivity just we will go through the scenario a dedicated DHCP server is scalable and relatively easy to manage but it can be costly to how one at every location in a network however a Cisco router can be configured to provide a DHCP services without the need for a dedicated server as the network technician for your company you have been assigned the task of configuring a Cisco router as a DHCP server you are also required to configure the edge rotor as a DHCP client so that it receives an IP address from the ISP network ok so this is our objective we will let configure our router as a DHCP server we will configure DHCP or relay and also we will the configure router as a DHCP client we will go through the instructions one by one coming to Pat one configure a router as a DHCP server step 1 configure the excluded ipv4 addresses first of all we will configure these excluded ipv4 addresses addresses that have been statically assigned to devices in the networks that all use a DHCP must be excluded from the DHCP prunes this avoids errors associated with the duplicate IP addresses in this case the IP addresses of the r1 and r3 land interfaces must be excluded from DHCP in addition nine other addresses are excluded for static assignment to other devices such as servers and device management interfaces so here we will configure r2 to exclude the first 10 addresses from the r1 LAN so here are they given that command we have to go to global configuration mode in r2 then we have to give this command IP dhcp excluded address and here we have to give the lower address 192.168.1.1 starting from 10.1 and it till that means the higher address 192.168.1.1 so we will exclude from 10.1 till 10.10 ok we will do this configuration coming to this rotor r2 we will go to CLI yeah enable we have to go to global configuration mode kind of T and we will give the configuration IP dhcp excluded address we have to give the stack address 192 168 10.1 will protect a shin mark here and we can see we have to specify the low IP address 192.168.1.1 then again I will put a session space and question mark and we can see hi IP address so we will give a till 10 192.168.1.1 ok one ninety two dot one sixty eight dot 10.10 then press Enter now coming to be configure to exclude to the first certain addresses from our three LAN so coming to our topology here we configured I mean be excluded ten addresses from this our one line here we can see that from this network over 92168 10.0 now we are going to exclude the first written addresses from this art wheel and here we can see that our three LAN 192.168.0.0 so we will do that configuration in this over our two we will do that here IP dhcp excluded address one ninety two dot one sixty eight dot it's a 30.2 one this is the lower address then we have to specify the high IP address one ninety two dot one sixty eight dot thirty dot check then press enter now we will go to step 2 create a DHCP pool on our two for the r1 LAN so create a DCP pool named r1 - LAN and the specific it is a case sensitive because it's only for a scoring purpose otherwise you can specify the appropriate a pool name here we have to use this the same pool named Arvin - lon here we can see that IP dhcp pool r1 - land ok we can do that sure we will give I P DHCP pool then we have to specify the pool name as specified r1 - LAN then press Enter next is configure the DHCP pool to include the network address the default gateway and the IP address of the DNS server ok and here are they given the commands for this configuration network 192.168.1.0 then we had to specify it to mask then we have to set it is a default rotor and that means the default gateway ah nine two dot one six eight dot ten dot also they given the DNS server so this information began asset in this pool our one dashed line we will give that command first we will give the network its so one ninety two dot one sixty eight or ten dot 0 then you have to give it to surf in to mask its here then presenter no we have to give the default rotor it's one ninety two dot one sixty eight dot Tendo to one also we have to give it's a DNS server one ninety two dot one sixty eight dot twenty dotted 254 then press enter now coming to step three create a DHCP pool on our to for the are three LAN create a DCP pool named are three dash LAN and if this is also case sensitive then configure the DHCP pool to include the network address the default gateway and the IP address of the DNS server refer to the addressing table now we will configure a pool a DHCP pool of for this are free land we will go to our two and we will exit from this DC people we will give I P DHCP will create the pool as a three - LAN right then we have to give the network first it's a one ninety two dot one sixty eight dot 30.0 then it's a certain to mask you can verify that here it's a slash 24 yeah then press enter now we have to set its IP default rotor it's so one ninety two dot one sixty eight dot 30.2 one even we can verify that from our addressing table here we can see our three G zero zero one nine two one six eight 30.1 which is connecting to this network so I will show that interface here G 0 / 0 so we given a default router IP address okay it's not IP default router we have to give only default router yeah default - rotor then the address no we will I set a DNS server it's same what we given here coming to a dressing table we can see that a trusted DNS server address so just copy and I will paste here Oh Kendra okay no coming to party to configure a DHCP relay step 1 configure r1 and r3 a set DHCP relay agent for a DCP clients to obtain an address from a server on a different LAN segment the interface that the clients are attached to must include a helper a truss pointing to the DHCP server in this case the host on a lands that are attached to r1 and r3 will access the DHCP server that is configured on r2 that's right and cura they mention who is this helper address the IP addresses of the r2 serial interfaces that are attached to to r1 and r3 are used as the helper addresses DCP traffic from the host on the r1 and r3 lamps will be forwarded to these addresses and processed by the DHCP server that is configured on r2 right so here we are going to configure this helper atras in this r1 land as well as in this are three line and if you are going to configure in this interface that is G 0/0 and here the IP helper address for this Arvin will be the IP address of this interface in this r2 that is 0 0 0 0 and the IP helper a trust for this r3 will be the IP address of this interface I mean this r2 interface serial Ciro's not 0 / 1 so that you know this r1 and r3 can send this a DHCP request to this router r2 ok so here we can see configure the helper a trust for the LAN interface on r1 ok first we will do it in this router r1 we have to go to that interface that is a G 0 slash 0 which is connecting to this network I will show that interface G 0 star 0 in this worker r1 this interface then we have to give IP helper address 10.1.1.10 throw face CDLs 0 / 0 / 0 or in this router r2 so we will do that configuration we will go to our 1 CL line ok enable Kunti we will go to that interface that is G 0 / 0 and we will set that IP helper address it's a 10.1.1.10 no configure or the helper a trust for the line interface on earth way so here we can see you have to go to this interface that is a G 0 / 0 which is connecting to connecting this network right how can we will do that we will go to r3 enable Kunti we will go to that interface G 0 / 0 and we have to set that IP helper - atras so what is the address coming to our topology I will show that the IP address of this interface that is let me check it CL 0 / 0 / 1 this rotor r2 so that address we can take from our addressing table our two serial 0 / 0 / 1 sure we can see that it's a 10.2.32 okay we will luck configure here as a IP helper address 10.0 - dot - coming to step to configure a house to receive IEP addressing information from dhcp configure has two pc1 & pc2 - will see with their IP addresses from a DHCP server coming to our topology here we can see pc1 & pc2 so we will go to pc 1 and we will give a DHCP option just click on PC 1 then go to IP configuration and - sure we can see now be selected isostatic so we will click on DHCP so that this PC will request for the DHCP - this a DHCP server and he will receive with the IP address here we can see DHCP request successful and he received IP address and here we can see sir to mask a default gateway DNS server also will go to PC - IP configuration click on DHCP and requesting yes DHCP or cost successful so we can see ie Pietrus certain to mask a default gateway and DNS server and we can see these societies from 192.168.0 network we're afraid that - the host have received their addresses from the correct DHCP pools yes this is 192.168 out 10.0 and we have seen is from the from that network over 92168 10.11 ok and here are we have seen it's a 30.0 so we received a peridot 11 now coming to power 2 3 configure a router as a DHCP client just as a PC is able to receive an ipv4 address from a server your router interface has the ability to do the same Porter r2 needs to be configured to receive addressing from the ISP so coming to a topology here we can see our router r2 and this interface I will show that it's G 0 / 1 we have do a same DHCP so that this interface will receive with IP address from this is P hence a we will configure the Giga be the current 0 / 1 interface on r2 to receive IP addressing from DHCP and activate the interface so here we can see the command we have to go to that interface that is a G 0 / 1 and we have to give IP address so instead of IP address we will give a DHCP so that we will get the IP address from the ISP then we have to activate this interface by this command not shut down we can do that we will go to r2 presenter enable Kunti we will go to that interface that is a G 0 / 1 and we will give the IP address as a dhcp then press enter also we have to activate this interface no shutdown they given a node use packet racers fast forward time feature to speed up the process you know sometime it may get a delay to get the IP address for this interface from this is B so just you can fast forward it time here click on fast forward maybe twice or Trice okay now use the show IP interface brief brief command to verify that are to receive an IP address from DHCP we are going to verify it so just click on r2 then press Enter and we will give end here we will give the short commander show IP interface brief and we will let check that interface at G 0/0 the max may sit here we can see it's G 0 / 1 right we can verify it oh it's G 0 / 1 yeah it's G 0 / 1 here we can see G 0 / 1 and we can see it received the IP address you can see that just and see the method we given DHCP will not configure manually be given DHCP and this interface sir receive the IP address from the DHCP server and we can see status up protocol also up now we will go to part 2 for verify DHCP and connectivity verify dhcp bindings we have to give this command show IP dhcp binding so you will do that we'll go to r2 and give that command show IP dhcp binding so that we can see the details here we can see 192.168 or 10.11 is a saint also 192.168.0 11 is a saint so it's a saint to these pcs that is pc1 & pc2 this a trust that is 192.168 or 10.11 is assigned to this pc 1 then 30 dot 11 to this pc 2 and we can see other information it's a hardware address that is the MAC address of that PC and the lease expiration not given ok and the type is automatic coming to the last step verify configurations verify that pc1 & pc2 can now ping each other and all other devices ok we will try to ping from pc1 to pc2 we will go to pc 1 command prompt and we will ping to this pc to give the command ping and the IP address of pc 2 one ninety two dot one sixty eight dot thirty dot eleven maybe we will get one North to lip goes to timed out don't worry about that yeah and here we can see we get the replay Center for or received three polka just press up arrow from keyboard up arrow then so we will get the same command to be entered so just press ENTER again and we can see beak at the replay Network involved okay great one of the interesting and you see configuration that is configure DHCP version four and here we can see the completion status of this activity it's a hundred percent now dear friend if you have any doubt any suggestions regarding this activity you can comment below or you can contact our team using our website so stay tuned for the future videos we will meet again with the next video thank you
