Inter VLAN Configuration plus IP- Helper Address

This lecture is part of one of my courses that encompasses several concepts of the CCNA certification. In this lecture you will learn how to configure inter-VLAN connectivity and the importance of trunk ports. To view the entire course, which consists of Access-list, NAT, VLAN creation and assignment, Ripv2 and basic Router administration, go to www.thenetworkingdoctors.com website or the www.GlobED.net website!
Hope to see all of you as one of my online students!

This video taught me more about inter-vlan configs than the hours i've spent in lectures and doing coursework, thank you!

[@thenetworkingdoctors]

Your welcome, I am glad I was able to help you.

[@peterhenry3840]

i understand why your lessons are so easy to understand, just because easy is part of your name, the only thing we have to do is play it over and over again. I read through most comments and i find out that 2 years ago someone commented on this video and 5 minutes ago as well, people keep watching and it wont stop, it sounds like you did the video few minutes ago. Mr. Easy! You too good, thank you for your support, we will keep learning from you till we do like you do or more, i really appreciate, we love you.

[@jairobenavides2456]

The ip helper-address is what i had been troubleshooting for a long time, only to find out The solution was on a 18min video... Definitely a great tutorial. I loved it.

[@cr7cubanocr7]

Cool, and thank you for the response I admire your work not only because I'm Cuban as well lol...but because I'm also in the networking world and it's a privilege to have professionals like you who are willing to take the time to help others.

Really good teacher. Better than Universities some how

[@KamiKami]

Best teacher I've ever watched!

[@thenetworkingdoctors]

You are correct, you can setup the router as the DHCP server and it would simplify things. This was a lab demostrating the 'IP helper-address" withing a VLAN enviroment. But take care on which router you would setup the DHCP service, make sure is not a router handling lots of traffic or is already burdened with other services.

[@FrameSimon]

I don't normally comment on any video but, mate, you just gave me the info I needed to solve this f-cked assignment I got. Brilliant teacher, thank you.

[@uosefshaaban4763]

The reason why you are gorgeous is that you simplify the explanation Thank you :)

[@HSFServicesInformatiques]

Hi Laz, Great tutorial! Please can you explain me why do you use the switch interfaces instead of doing the sub-interfaces on the router? g0/0.2 for exemple.

[@Aswinvishnu2]

grt thanks comming from india

[@tsupport5514]

very well thanks it helps a lot

[@thenetworkingdoctors]

[@mcse112]

Hello Laz, just want to say excellent job with the tutorial, you made it very easy to understand. I just have one question, I have a SG300 switch which can do inter VLAN routing and am using a Asus-68U wireless router to do my wired and wireless routing on my home network. I'm trying to setup a lab that contains VLANS and want them to have access to the internet. How can I accomplish this without an actual router since i cannot add subinterfaces to the Asus-68U wireless router.

[@lamp4616]

You're my saviour.

[@thenetworkingdoctors]

+Lamp ...thanks Lamp!

[@thenetworkingdoctors]

@mohammed gesmalla...this is a snippet of my complete Vlan course available on Udemy.com. The complete course is over 3 hours long.

[@bharanibabu1]

excellent sir:)

[@djkrz]

Hey Laz... Great videos bro...I wanted to ask you if you can let me know where can I find the previous video of this lab or the whole lecture videos, it would be amazing, im not able to find them and I really want to view them, so i can be on the same page you are on this video. Thank you very much for your help, and amazing work on your video tutorials Kenny

[@scott2495]

Hey Laz, love your videos my man. I am guessing you would have to nat translate each of the sub interface default gateways to one public ip for outbound internet access?

[@bodybychiken]

Can you attach a pic of the ip configs? Couldn't really see them on the vid. Thanks

[@srabbasy9425]

Great. Thank you

[@hannahjoyvelasquez6942]

[@journaltap1]

hey laz is there a video that shows how your setting up the toplogy. just finished my cisco 1 course and would like to see how your setting up your devices as well as your interfaces so i can rebuild it on my packet tracer. this seems like it would be a great review before i get started with my cisco 2 course.

[@rodrickkatumbayi7222]

hello sir, i would like to know about configuration of the trunks for the access switches ?

[@thenetworkingdoctors]

@Ryel Dsouze...I use the cisco packet-tracer

[@eversmilebala]

Hi Dude, Its very useful, but i would like to learn about Windows DHCP server along with Inter Vlan concepts, can i get any link for my question? Thanks in advance

[@joser1083]

How can i route my vlans to get internet access. am STUCK BIG TIME. I have vlan 10,20,30 on a 3550 switch, and a 2821 Router vlans can communicate to each other but not the internet. ACCESS-List looks fine ? any advice ?

[@domahdaniel63]

Thanks so much

[@thenetworkingdoctors]

You’re welcome!

[@thenetworkingdoctors]

Thanks brother, I believe the Packet Tracer is free all you need to do is search for it. Udemy has nothing to do with it. If you can find it I can always setup Drop Box or an FTP for everyone to download it. I going to see if I can make it available as link as part of my lecture. thanks again for the great comment.

[@ITsupportian]

That's pretty good.

[@unicohijo77]

how to setup the packet tracer like you do when you minimize the cli of the devices it will become like a tabs below?

[@seanc846]

This guy is fucking fantastic!!!!

[@wendellngavataroa2620]

I have a situation here, had a router, one switch to be used for vlans and a Dell server running Windows server 2012 R and would like to have all ip addresses all dynamically deployed via the Server 2012 R2 utilizing IP helper from the router, any configuration ideas for this set up?

[@anilrevannavar4014]

Good tutorial

[@thenetworkingdoctors]

Glad it was helpful :)

[@beautywithinsherry7141]

Do you have a video that shows how you configured the whole network please? Also i wondered whether you have a video that explains inter -vlans configs that incorporate an email server?

[@thenetworkingdoctors]

@Soroosh Kia ... The packet Tracer file is at Udemy.com when you register for the full course

[@mohammedgesmalla8833]

it's great video and you are my favorite ..but where is the rest of configuration ..?

[@thenetworkingdoctors]

@alex yu, my first question would be is this on the same switch or do you have multiple switches with multiple vlans? my sencond questions is can you ping other vlans? If you can't ping other vlans, my third question is did you trunk your ports? Based on your question I can only deduce that your tagged vlans are trying to get accross a non-trunking port.

[@MrLeonScott]

A have a question: for example, if your NAT Router were the DHCP server, how would you configure the Access Router (in WAN connection between them) to provide all the hosts an IP address, in the diferent VLANs? Hope you can help me, thank you!

[@Badboiz55]

QUESTION!? IS it possible to connect two Cisco router trough T1 CSU/DSU and have Vlans on both Router 1 and Router 2 communicate with each other? because i config the T1 CSU/DSU interfaces on both routers and i was able to ping but i cannot ping Vlan to Vlan, I'm new into Networking I'M not sure If i'm missing anything

[@thenetworkingdoctors]

@Cubano Madrileno....in this video I am only trying to show the use of the IP-helper command. Therefore, I used an actual server in a different broadcast domain to demonstrate how a host on another broadcast domain can get assigned an IP address, by using the IP helper-address.

[@lekulahowangahaora8733]

can please repeat how you do your calculation to accending the ip address and subnet mask sir?

[@jatinprasad7341]

Great

[@runescapeblub]

I connect a router with a switch, and that switch with an other switch (so R-S-S). And I have on switch one Vlan10 and 20 and on switch two vlan 30 and 40. I configure the trunk link between R-S and S-S with trunk allowed 10,20,30,40. And I do the encapsulation and everything. Plus my router acts as a DHCP . My hosts in vlan 30 and 40 do not receive an IP as long as I didn't issue the "int vlan 30" and "'int vlan 40" command on switch one. What is the reason for this? Can you explain this? Or is this explained in a video somwhere?

[@next12win]

Thanks for the reply! Let me know if/when you're able to offer it as a link and I will certainly sign up.

[@djKenpLan09]

Question, why did you use the last available IP and not the first one? Just preference? Thanks in advance

[@petervu9773]

hi question ! you're using class A range ip with class C subnet mask...im confused .. can anyone elaborate ?

[@alishahrasouli8562]

Hi dear sir: thanks for these useful and great videos. sir i followed all steps as you did. but when i renew the ip address on vlan 10 or ..... the dhcp server assigns ip address from 10.100.0.10 and for the next vlan is 10.100.0.11 and for the next is 10.100.0.12 here is my question that why it is not assigning ip address 10.100.0.64-..... for the second network.??????

[@getobilgates467]

Hey Guys, I have a situation where I have a switchport that is on vlan 10. So all devices that are connected to that port are on that subnet. Howver we have just installed some ip cameras in our yard that are on a different subnet , subnet 192. Two of these cameras are connected to the network that is on vlan 10. How can I route the traffic on these 192 cameras to vlan192? Sorry if this is not the right place for this question, but can you please point me in the right direction?

[@sauravanand628]

Sir I have a question, I want to set up a specific web page on my router so that any client machine(phone) who connect to my router will automatically get the same web page which I have set, in their browser. Is is possible to do and how?

[@joser1083]

How can i get my Vlans to the internet ? i have a 2821 router and a 3550 switch ? am not using Sub interfaces ? My Vlans can talk to each other but not the outside world? i have Nat on the router configured. Need a little help Thanks !

[@zsoltb5928]

Yee I like your videos

[@IshaqKhan-qp3vk]

Sir I have a doubt, how can I configure 2 different ip address in a switch and make them ping

[@TheAmazeer]

Hi laz great video! One question do you think wol is possible between server vlan (dhcp, dns, ad...) to computers vlans.. I need to wake up my computers from the server which is always turned on and already configured with two dhcp scopes (2 vlans 1 for teachers 1 for pupils).. Our network core is a level 3 cisco switch... As wol doesn't traverse routers even if ip-helpers allow broadcast from computers to dhcp vlan server it doesn't allow wake on lan from vlan server... I thought about using a trunk between but if so no ip-helper will be configurable in that trunk I guess... I hope I was clear enough to hope having an answer from you... Thanks a lot for your help dude

[@umarhayyat9263]

if you assign the inter VLAN to router why you attach a DHCP server you created a server on the router so why you attach the DHCP server

[@jmoncctchi641]

can you please leave the link for the cost of training material for the CCNA and how to purchase material

[@michaelwatt717]

I have a question. i am sure there is a security reason behind it. But why use the last number in the subnet to address the VLAN. I only remember on question that did that scenario on the CCNA. But why not 2 or 3 rather than 30 of a /27.

[@niconic9062]

Hi I get native vlan mismach when I have finish to config vlan 2, how to fix that????
