BGP routing with NVA in Azure vWAN hub

Question

Hi,

This is regarding setting up NVA in Azure vHub and run BGP for route advertisement. The scenario in question is what is shown in "Direct Interconnect model with NVA-in-VWAN-hub" at https://learn.microsoft.com/en-us/azure/virtual-wan/sd-wan-connectivity-architecture

The question is that while running BGP between the NVA and the vHUB, is the BGP run between vHub router and the NVA or is it run with hub VPN gateway? In case BGP is run between the vHub router and the NVA is this feature general availability as BGP support for vHub router is still in gated preview.

Thank you.

Answer 1

@Pankaj Sharma Thankyou for reaching out to Microsoft Q&A. I understand that you are having questions regarding BGP peering between NVA and vHub as shown in the "Direct Interconnect model with NVA-in-VWAN-hub" architecture.

Please note that the routing capabilities in a virtual hub are provided by a router that manages all routing between gateways using Border Gateway Protocol (BGP). A virtual hub can contain multiple gateways such as a Site-to-site VPN gateway, ExpressRoute gateway, Point-to-site gateway, Azure Firewall. As per your second question, yes, BGP peering with a virtual hub feature is still in gated public preview.

If you are interested in trying this feature, please email previewbgpwithvhub@microsoft.com along with the Resource ID of your Virtual WAN resource. After receiving confirmation of feature enablement, please follow the following doucmentation page for key considerations and a detailed configuration guide.

To locate the Resource ID, open the Azure portal, navigate to your Virtual WAN resource, and click Settings > Properties > Resource ID.
Example: /subscriptions/<subscriptionID>/resourceGroups/<resourceGroupName>/providers/Microsoft.Network/virtualWans/<virtualWANname>

Hope this helps. Please let us know if you have any further questions and we will be glad to assist you further. Thank you!
