Thank you for taking the time to make these vids, they are really straightforward and helpful

This is just fantastic. Thanks for all the tutorials. Your narration style is excellent and makes complex subjects simpler to understand. Thanks again.

Thanks for the awesome vids! For anybody curious, another way to check what the Native VLAN is for a trunked interface--if we assume fa0/1 as the trunk--is to issue the command: S1# show interface fa0/1 switchport ======================================= Name: Fa0/1 Switchport: Enabled Administrative Mode: trunk Operational Mode: down Administrative Trunking Encapsulation: dot1q Operational Trunking Encapsulation: dot1q Negotiation of Trunking: On Access Mode VLAN: 1 (default) Trunking Native Mode VLAN: 55 (Native)

This is the most complete series I could find on this topic. Nicely done!!

Dear Dan, thank you so much for all your tutorials help, I passed my ccna exam today. You've been so helpful, I really appreciated all your hard work on your A-Z CCNA prep videos.

Thank you for taking the time to make this videos. It's a great resource and it's greatly appreciated.

Sir you are a legend.. Thanks for making all these videos and making it easy for us to understand..

The switch only needs an ip address and gateway address if you want to be able to remotely connect into it (to manage it) and once your in it you want to be able to connect outside of the subnet. The native vlan is a vlan designed to be backwards compatible with older devices that do not support VLAN tagging

it was great that you made that little mistake with the native vlan(77), because allow us to know how to troubleshoot that and fix it, without freak out in the exam or a job interview...Thanks for the videos they are very helpful.

Thank you so much. U saved me. Tomorrow is my demo to show this all and It is just 7 hrs away from me. Thank you.

I love your videos. Very real world and clearly explained. Great job!!!

VLANs are to seperate traffic into different broadcast domains. The only way they CAN communicate is with a Layer 3 device (a router or Layer 3 switch). Even then you have to do similar configurations on that router or L3 Switch as what Dan did here for them to see each other. They don't HAVE to talk to each other. If they should or shouldn't depends on your network design.

That was very helpful. Thank you for making it easy to understand

Thank you for sheading light on a difficult subject

Watching this tutorial in 2020😍Love it

Thank you for the explanation, it helped me understand the routing part

Thank you for an explanation on this interesting topic. It was very informative and i appreciate your help.

Excelente leccion! Muchas gracias, gran ayuda!

Awesome videos. Very clear and concise.

that's really amazing!!!!!!!!!!love love love love!!!!!! Never get confused again!!!!!!!!

Nice video. For the noobs like me who may have run into this: You also need to configure each of the 3 computers with the ip addresses indicated and their corresponding gateways. Took me a while to catch that.

it won't ping any other pc bcz each vlan have own network it only ping to router.. but it can also ping to other pc/vlan u need some further configuration and connection with router.

Great tutorial, thank you very much!

absolutely!

Really helpful to understand thank you very much

Well explained Thanks! I've been preparing for my CCNA with Boson Netsim but found it's a little buggy and limited on commands due to Boson's IOS. Switched to running Boson's Labs by setting up the labs in Packet Tracer. Used these videos as a guide to completing my interVlan lab.

Very descriptive. The best for beginners :-)

your videos are amazing!

Many many thanks for your great help!

Awesome tut, thanks very much :D saved my bacon for my uni assignment! ^_^

I actually love you, thanks!

it is a wonderful lesson, i like it all!!

hey man, thanks for this video helped me a lot :)

Great videos. Thanks

You are the best bro

Hi Dan, Thank u for the time u give us. Can we trunk native vlan without adding vlan 55 to the allowed trunk? It seemed like we trunk the native Vlan 55 twice. Thank you

very useful.....thank you very much~~~

Thank you!

you are amazing !

This was a great video... my question is.. what brands of routers will work? Does it have to be a Cisco?

million thanks, its really help !! ^_^

Thank you thank you

work job thanks!

thank you so much for uer answer .. because i confused when i did the same thing in video and i found the vlans ping each other .. So previously i thought that vlans shouldn't communicate with each other ..

Dear Dan amazing video, but could you please explain the need for configuring default-gateway on the switch and encapsulation dot1Q 55 "native" command ???

I did full tutorial, Am i supposed to be able to ping the Native VLAN from the other networks? (.10... .77)

Hi thank you, I'd appreciate if you could answer this, does the default gateway of each PC need to be set to the address of tge sub interface?

Great series with really good instructions. Do have 1 questions though. If you wanted to assign a management IP address to the router (192.168.77.3 for example). How would you go about doing this? I've tried: interface fa0/0 Ip address 192.168.77.3 255.255.255.0 but get an error of "IP overlaps with FA0/0.100. I also tried simply SSHing to 192.168.77.1 but that times out.

Will this work for all vlans on different floors and switches? Also would using VTP effect the configuration?

Hey Dan...all your videos are great...Just one question here...Should we not be able to telnet into the switch through the laptop???bcoz hen i am trying to its saying connection closed by foreign host??

thanks bud

why do we need to configure the allowed specific vlans in the trunk link between switch &router?? if we left it without configuration will it affect the link traffic?

How can you make static routes across more than one router WITH vlans spreading through out the routers on the other end?

Hi, Thanks for all the video's, they are very helpful. At the start of this example there where 3 switches running into one router on a stick. Could you point me to a video of this please. Or explain how to add extra switches to this example. Thanks

you can't have another network on the same interface regardless if tis sub inf or not (your gigabit6/0, physical interface already configured with the same network address and your trying the same network address on a sub-interface of the interface 6/0 ND therefore ultimately you will get this overlapped error message. leave the physical interface blank and configure the sub interface instead.

Nice. But on this scenario, is it possible to config the DHCP on the router. To provide dynamic IP Addresses to the PCs?

dzieki wielkie POZDRAWIAM (PL)

the ip addresses for subinterfaces on the router - are they some new addresses that dont matter much or are they somehow connected to addresses of each VLAN? I mean do I just come up with some random address or does it have to be somehwo specific.

I had check all configuration of router and switch. It is also right. But i cannot ping the different VLANs

I think it's because dot1q encapsulation isnt enabled on the switch trunk?

Am i need to set up the default gateway in each VALs?

I noticed that routing is working fine even If I didn't put that last configuration 'native' when configuring encapsulation for the sub-interface 0/0.55 of the router! Any explanation?

From my experience native vlan mismatch does not necessarily stop routing from working, ... but it does create annoying console messages.

why to set a default gateway for a switch??without we generally ping between two different networks with router gateway being enabled on end devices.so can we skip the gateway setting on switch or is it mandatory

I think he said that up so that the Management PC i.e., the one on the VLAN 77 can telnet or ssh into the switch for Management purposes. However, he hasn't configured telnet on it.

Did you configure your vty ports on the switch to allow access?

According to this diagram, can i get ping response 77.2 (Switch IP) from Cisco Router???

Is there any tutorial about Layer 3 switch?

What version of packet tracer are you using?

Now how we can have access from one of the PC to cloud? I have configure router fa0/1 with DHCP which would be uplink to my cable modem. but I am not able to go online from any VLAN. I am talking about my lab.. I configured one real router 2431 and switch 3650 and create same vlan like ur video class.

Do you have any tutorials for GNS3?

thanks how do i tellnet into the mangement vlan

What was the point for the VLAN 55 if it hasn't been physically connected?

I did this in packet tracer and i cannot ping the router from my switch and vice versa

Why do you allowed vlan 1?? If you allowed in trunk native vlan 55, the native vlan 1 is only in the switch in the trunk vlan 1 is vlan 55.

So how come none of the vlans on the router do not have ip addresses? I did everything here and it shows the vlans on my router as administratively down/with no ip I can only ping the gw

Everything works, just wondering why if it is replicating why it doesn't show the ip for vlans on router thanks

can anyone pls tel me what is the use of creating the vlan interface 77 ??? i didnt got the point of creating it ?

5:45 what if your vlan number is higher than 255? that doesn't fit in an ip address?

i have a question sir.. is it the VLANs shouldn't contact each other ? or they have to ?

can you show a configuration with a router on a stick with one switch and multiple vlans on the switch, ip addresses ceated with vlsm subnetting. My subinterfaces keeps showing conflict with the first subinterface. Example Router(config-subif)#ip address 172.16.0.1 255.255.0.0 Router(config-subif)#int gig 6/0.20 Router(config-subif)#ip address 172.16.1.1 255.255.0.0 % 172.16.0.0 overlaps with GigabitEthernet6/0.10 Router(config-subif)#

I configured the router and switch like you. But I can't ping different vlan

becouse encapsulation on router port ... :)

that native vlan 55 won`t work. if you had configured a client without any vlan`s and try to ping that 55 native - you would not succeed. the native vlan between the switch and the router MUST stay at default #1. the only time you can change the native vlan is when going from switch to another switch, then you can do whatever native vlan you want. between a switch and a router it must stay 1

+Atzeni a I`ll try to explain that a little better: if you are a native vlan 55 and you come untagged to the router, the router will first search the physical interface and if there is no match over there - it will search for the "native" statement in one of his sub-interfaces. try to configure this 55 sub-interface on a physical interface and you`ll see it works just fine but if you are at native vlan 1 and you come to the router untagged - the router WILL NOT search the physical interface at all. it will only search in his sub-interfaces for example, you are at 192.168.99.100 and your native vlan on the switch is 1. because you don`t belong to any specific vlan you are by default vlan 1. so leaving the switch (which it`s native vlan is 1 as mentioned) you supposedly do not have to configure a sub-interface, you are untagged, so you should be able to address the physical interface (as you did when you were 55) - but you`ll see you won`t be able to. you will have to create a sub-interface with the native statement ALTHOUGH you are travelling untagged. that is why there can be no possible way you were vlan 1 and successfuly pinged a vlan 55 native - the frame would come with the "vlan 1" tag to the switch and there it will see that the native is 55, so it will send the frame tagged as usual. the frame would enter the router as vlan 1 and there would be no sub-interface to welcome him aboard. thus, the frame would be dropped. try it and see it`s true.

How, and what are the steps?
