Azure VWan hub to hub connect across two tenants in same region

Gopinath Rethinam 20

Hi Team,

I have Two azure tenants in same azure region. In both the tenants I have a dedicated Azure VWAN with one hub in it. I am trying to connect this two hubs across tenant so resources under both hub's spoke can talk to each other. I am not able to find right documentation or solution for this. Kindly help us here.

All I can see is this link https://learn.microsoft.com/en-us/azure/virtual-wan/cross-tenant-vnet which expalin connecting a Vnet across tenant.

Thank you

Hi,

I understand the limitation and will put a feature ticket. As of now we are in the implementation phase. Kindly provide a detailed document which explains connecting Vnet from remote tenant to the current tenant which hold Vhub.

Below link doesn't explain about how user assignment will happen across tenant, Please give me right document which explains step by step to connect Vnet from remote tenant to my tenant vhub

Hi @Gopinath Rethinam,

We appreciate your feedback and apologize for not providing a satisfactory answer to your query earlier.

As we discussed earlier, connecting a Hub in VWAN A to a Hub in VWAN B across the tenants via the normal VWAN hub to hub mechanism is not currently supported today.

But for workaround, we can connect vHub in VWAN A to vHub in VWAN B using VPN gateway of the Virtual Hubs.

Refer: https://learn.microsoft.com/en-us/azure/virtual-wan/connect-virtual-network-gateway-vwan

To answer your question,

You can manage cross-tenant virtual network connections only through PowerShell or the Azure CLI installed on your local machine. Because Azure Portal does not support cross-tenant operations, you can't manage cross-tenant virtual network connections through Azure portal or Azure portal CloudShell (both PowerShell and CLI).

You can use the PowerShell to connect a Virtual Hub of a vWAN from a virtual network which is sitting in a different tenant.

The detailed explanation is clearly mentioned step by step in the below document. Please refer to it and let us know if you have any other queries.

For your reference: https://learn.microsoft.com/en-us/azure/virtual-wan/cross-tenant-vnet#prerequisites

Kindly let us know if the above helps or you need further assistance on this issue.

Thanks,

Sai.

Hi @Gopinath Rethinam,

Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.

You can use Virtual WAN to connect a VNet to a virtual hub in a different subscription/tenant but connecting a Hub in VWAN A to a Hub in VWAN B across the tenants via the normal VWAN hub to hub mechanism is not currently supported today.

If you wish, you may also leave your feedback in the below forum requesting this feature. All the feedback you share in these forums will be monitored and reviewed by the Microsoft engineering teams responsible for building Azure. https://feedback.azure.com/d365community/forum/8ae9bf04-8326-ec11-b6e6-000d3a4f0789

But for workaround, we can connect vHub in VWAN A to vHub in VWAN B using VPN gateway of the Virtual Hubs.
