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!
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 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..
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"
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.
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.
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?
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?
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, 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.
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
Hub and spoke is the preferred way to connect multiple VNets. The caution is about using a VNet gateway as the router. VNet gateways are made to encrypt traffic and although they will work, Microsoft recommends against it. learn.microsoft.com/en-us/azure/architecture/networking/spoke-to-spoke-networking?WT.mc_id=AZ-MVP-5004159#pattern-2-spokes-communicating-over-a-network-appliance
@@Ciraltos Thanks for your responsem what about in a site to site context using the virtual network gateway transit setting in the VNETs peered to the HUB is that considered ok for production?
