Azure Hub and Spoke Virtual Network (VNet) with a VPN Gateway

In this video, we create a hub and spoke network in Azure by peering our spoke VNet’s to a centralized, Hub Virtual Network. Then we use a VPN Virtual Network Gateway to enable gateway transit connectivity between the spokes. Next, we configure routing with Azure Route Tables and User Defined Routes (UDR) to send traffic going to other spokes to the hub. Then we log into a virtual machine and verify connectivity.

Amazing video. one of the best, shortest, for profession by profession videos... Most videos on this topic, insist on walking you over "what is a VNET". This get's to the point fast!

[Wilhelmcook]

as always, brilliant and to the point introduction. Thanks

[neeharikagv]

Thank you so much for this video. This was one question during my interview few days ago. Also I didn’t understand what exactly is ‘hop’ which makes sense now from this video. Thank you Sir..

Great video, I did not know one could use a VPN Gateway as a router. Having said that, regarding what you said about being complicated by the need to create a route table per vnet, if you are using a third party NVA in the Hub network, you can create only one route table with the default route pointing to NVA ip address. Then this could make things much simpler. Of course you need the proper configuration on the NVA itself.

Thank you so much for putting this together. I have been trying to figure out my vnet to s2s vnet routing for hours and could only find resources talking about azure vnet to vnet, but you talking about route table made it all click! Duh! Why didn't I think, "I wonder if there is a route table"

[smeyyappan]

Awesome ! You make everything look so simple. That is Great !!! 🙂 Thank you May God bless you.

[AAhmed_Alii]

Very helpful video, thank you! Is there any way that allows automatic route adding in the route tables? That would make the process much simpler for large scale solutions.

[tendaimusonza]

liked the video right from the first few seconds of introduction, great

[joaquincotilla]

Great video, thanks. Now, the same video but a Azure Firewall, please.

[peacejon]

Great Videos man 🙌🙌🙌🙌🙌 continue doing the Lord's work.... Can you do something on Azure Landing Zone?

[bloknath]

Great video. Is it possible to connect spoke1 to spoke2 without UDR or direct peering?

hi Travis, Excellent explanation. I have created a similar setup with 2 Spoke and 1 Hub networks in Azure. I have couple of queries,
1. I created RouteTable1 and assigned it to Spoke-1. Added a route to access Spoke-2 network via Hub VNET. Ideally, I should be able to ping the VM-2 from VM-1 since there is a route established from Spoke-1 and Spoke-2 network. But, I am unable to achieve. Unless I add RT-2 assigned to Spoke-2 VNET and add a route to access Spoke-1 VNET, then, I am able to access both VMs (ping each other). Why is it so?
2. After performing step (1), I went to Spoke-1 Peering (wtih Hub) and Disable the option "Allow 'vnet-1' to receive forwarded traffic from 'vnet-hub'". Ideally, this will stop traffic flow from Spoke-2 to Spoke-1 (VMs). But, I see the VM-2 is still able to reach to VM-1. Why?
Thanks.

Thanks for the video, is there a difference between configuring the peering from the HUB ? otherwise why you choose to create the peering from Spoke to peering ?

Hi Travis, I want to use a point-to-site vpn tunnel with vpn gateway to connect to four different azure subscriptions. What would be my best approach. Also I don't want these resources to share any data or connectivity with other subscriptions like dev and prod.

[kannanswaminathan]

Short and lot of details. Thanks a lot. I have an issue. I have hub and spoke model. i have a vm in hub and a vm in spoke. i use point to site. The issue is, i am able to RDP the vm on Hub but not able to control/RDP the vm on Spoke. Both the vnet's are peered. What could be the issue?

[sushantKarki-wk]

Wouldn't this cause delay because the traffic goes from the virtual network to other virtual network through the hub each time ? And this would get worst with any additional virtual network added to the system?

[prasantchettri]

Are you using VPN gateway as cost effective example for VWAN over S2S or ER?

[AndyRichardson-hh]

Morning Travis! can I ask why you dont recommend this for production? in terms of using the Gateway for the transitive routing as I use a similar set up in my production environment thank in advance

[stevenaudy]

Hi Travis, what about this scenario ? hub and spoke1 have own vnet gateway. how to set the route table ? i tried set it next hop to virtual network gateway, it's not connected.

[fortu]

what virtual machine are you using sir?
