Hello,
I've configured a multi-site VPN configuration for a client with the following structure. 2 Azure Vnets and 2 customer locations.
We are having connectivity issues during failover testing and tracing connectivity seems to be a monster with this configuration (tracert is useless from azure VMs).
When the VPN device fails at the customer's primary datacentre, we want azure to route traffic via the customer's secondary datacentre. In the local network configuration for the customer's secondary datacentre in our azure network configuration, Azure will not allow us to define the IP range of the customer's primary datacenter due to IP range overlap.
- Will the rerouting shown in the image below happen automatically due to dynamic routing anyway or is it not possible?
- If manual configuration is required is there any way to configure routing tables...etc so the scenario below will work?
I'm aware our customer will need to make configuration changes to ensure the internal routing works, but I just want to confirm that Azure supports this type of routing.
