Azure Network Routing to VPN and Expressroute

Question

I am trying to get Network Routing in azure between the below set up.

Vnet A - VPN Vnet B - Workload Vnet C - ExpressRoute

Each network will be peered to the Workload to allow traffic but no VPN Gateway option selected as Azure doesn't support 2 or more peerings with the VNET Gateway feature switched on. I have looked for other means using User Defined Routes.

I wanted to route any traffic as an example on 10.0.0.0/8 over the Expressroute and then any traffic on 10.222.20./24 over the VPN.

Now in theory I thought this would work but in practice it doesn't, the route gets confused where to go and ends up erroring out.

My research has led me to believe that its just not achievable without having an Azure WAN in the middle to control all the traffic?

Has anyone had any experience with this or used a different method?

Thank you in advance.

Hi James Tarrant "Work",

Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.

Azure Virtual WAN might indeed be a good solution. Virtual WAN provides a hub-and-spoke architecture that simplifies routing and connectivity between multiple VNets. Refer this link: Azure Virtual WAN Overview | Microsoft Learn
