Hey Keith, so grateful for this vid - was having the same problem and it was absolutely doin' my head in 😂. This seems be the same case for an integrated unit, like say the 829. I'll be duplicating this lab with a Cisco 897VA in my physical lab kit, so will be interesting to see if it's the same for the real stuff too 😋. Dude! This is my first comment since starting to watch your playlists a few weeks ago and wanted to say a huge thank you 😊👍 for putting out all this amazing content - SubnetSaturdays has been such a boost too, I thought it was going to take me months to get my head around subnetting but your teaching methods work so well. I believe the last few years have been a golden era for learning with so many educators such as yourself, Network Chuck, David Bombal and many others putting out so much quality content, both for free and very affordable access.

Thanks for the video tip! I have a 1921 with a EWHIC-4ESG and a 3750 and was having trouble understanding this just yesterday. Saw your post on reddit, viola. Perfect timing. Subscribed and looking forward to more videos!
Happy Birthday Keith. Love the Live videos and troubleshooting videos. Would love more content on packet tracer. I hope your channel g to number 1 in networking on youtube
Happy birthday 🎊 to the OGIT. I notice that in a real router with EtherSwitch Module, you can also use the regular VLAN command even if the contextual help is talking about ISL... I suppose that packet tracert support only the VLAN DATABASE command.
Hello keith, thank you so much for making such great videos. I always look forward to a new upload. I really like the way you explain the networking concept.
Aaargh, thanks for this. Been bashing my head trying to work out why 'vlan 10' did not create the vlan like it did on the router. Thanks for the #packettracer workaround
"vlan database" command on the router is applicable only on Packet tracer with switch module in the router or is this something we can use in actual enterprise network using putty ???
Mr. Barker, Thank you for all the fantastic content you put out. Does the CCNA go deep on layer 3 switches? all the materials I have seen mention it, but that's about it. I would like to focus my studies where it will get the best return. I understand they might be more popular in the wild than the test would have you believe. I can do a deeper dive after the exam if that's the case. Thank you in advance.
Thank you William Edwards. Feel free to join my Discord sever. Lots of people there helping each other out.

Thank you for the question Behzad Khayam. PC2 would use it's default gateway. That router (or multi-layer switch) would forward based on its routing table. For all the L2 connections between MLS2 and the other switches, STP would control which literal ports are used to forward. The costs for STP, and who the root is for VLAN 10, would be used by STP to determine the physical ports that actually forward the frames.
Hi Keith, you're doing amazing stuff for beginners ! Thank you so much for that. Would you consider to explain why we should use logical SVI's in stead of psyhical layer 3 interfaces on a switch (with no switchport command) or any loopback interface which is logical too ? Thanks and keep doing what you are doing is just amazing.
Thank you for the question Soner. Check out this playlist ogit.online/sloth In that playlist there are several videos about multi-layer switching and Switched Virtual Interfaces (SVIs) that I feel may help to answer that question. Check those out, and let me know if you have further questions, and if so I would be happy to elaborate.
Arijit Das yes, I a real work you can install a switch module. For example this is my scenario: I have a Cisco 2901 router with ADSL Interface for Internet, 02 GigabitEthernet interfaces, but I was needed additional interfaces with PoE for Access Point and IP Phones, so instead of buy a real PoE Switch that will take space and consume more power, I have just purchased a PoE EtherSwitch module and plug-in inside the Cisco 2901 and voilà, job done.
Thank you for the question Yassen Af. Unless the router has a switchport module, (and is not a multi-layer switch), it would not support an SVI (switched virtual interface).
Thank you Dhananjaya for the suggestion. Currently I am focusing most of my RUclips content at the Cisco CCNA level, but will keep your suggestion in the queue as a possibility in the future. Thanks again for the idea.
Thanks you for the content. Although informational, I am still confused about a few things. They are as follows: 1- Why would I put a switch module on a router, if, as you said, the idea is for a router to be involved on a vlan when I could use a multilayer switch with routing? 2- Going back to another video and lab; If I have a multilayer switch, connected to a router, with interface vlans on them, configured as default gateways, then how does one get the MLS to get traffic to the router of the interface in which it is connected? ( I have been wondering about this one for a bit) Thanks in advance.

Hi Keith. Thanks, for the wonderful videos. Can you please make a packet tracer video on Cisco.WLC configuration by using wlc 4404 controller. Actually, I am using mentioned controller in my campus network, with with bunch of 3502 aps. My clients drops the wifi for 5 seconds and than it comes back automatically. Is there any wlc configuration issues?
4404 WLC with 3504 APs, man those are ancient devices! Anyway, I'd start isolating the issue if it is SSID-specific, location-specific (any particular meeting room/floor, etc.), client-specific (identify the device type/client wireless adapter) and whether the client drops off of wireless or loses L3 connectivity, etc. Then capture the client debugs (you can keep the debugs running for a test client and wait for the issue to appear) on WLC to see what's going on.
Hmm I did this on real hardware with the same 4 port fast ethernet wic in my 1841 but my vlan 30 is up but down at layer 2.....I have to lab this again... Well i figured out my issue as I didnt realize the port fast ethernet 0/0/0 is read from right to left on the wic card... But now when I create the vlan on the 1841 from vlan database and do a show vlans it says the vlan does not exist and I get vlan mismatch errors between vlan 1 on my router and vlan 30 on my switch... I put the port's on the switch port module into vlann 30 but when I issue show Interfaces trunk I don't see the port's in vlan 30... Correction.... I found the vlan on my router, I had to use show vlan-switch command.. I fixed all the issues... I wasn't changing the native vlan to 30 on all of my devices and setup eigrp. Very good lab Keith thanks
Thank you Nanimo Nada. A device that primarily makes forwarding decisions based on Ethernet layer 2 addresses, is a switch. A device that primarily makes forwarding decisions based on IP layer 3 address is a router. A device the can do both is commonly referred to as a multi-layer switch. Happy studies.

You are so welcome
100k subs, good work deserves great rewards.
Thank you so much 😀
Happy Birthday Keith
Thank you Sankara!

Hi Keith, pc2 in VLAN 20 wants to ping pc1 in VLAN 10, how does R1-HQ forward the packet, and through which port/s? Please
Thank you for the question Behzad Khayam.
PC2 would use it's default gateway. That router (or multi-layer switch) would forward based on its routing table. For all the L2 connections between MLS2 and the other switches, STP would control which literal ports are used to forward.

@@KeithBarker Happy belated birthday! I too will join you at the great young age of 56 in June of this year!!! Wishing you many many more!!!
can we do a switchport int on that vlan you created on th e router
Thank you for the question Yassen Af. Unless the router has a switchport module, (and is not a multi-layer switch), it would not support an SVI (switched virtual interface).
Hello Keith ,what's the ifférence between ios and IOU images in gns3?
IOS is the operating system that can run natively on a Cisco router. IOU is IOS on Unix, that was designed to run in an emulated environment.
plz do a video about the VoIP configuration .....

I've heard of a later 3 switch, but a LAYER 2 ROUTER?!?!?!
Thank you Nanimo Nada.
A device that primarily makes forwarding decisions based on Ethernet layer 2 addresses, is a switch.
A device that primarily makes forwarding decisions based on IP layer 3 address is a router.
A device the can do both is commonly referred to as a multi-layer switch.
Happy studies.
Thank you
You're Welcome!
