Multiple Virtual Network with same range

Hi All,

I am very new to Azure just in starting phase to get more knowledge. I've a small query where i'm expecting solution

We have multiple customers in Azure . Assume i've customer 1 and customer 2. Customer 1 is using virtual network with 10.2.0.0/16 and customer 2 also using the same subnet range. Considering the scenario how Azure will route the traffic to exact destination. Reason for this question when we have hundreds of customers in cloud at some point of time there would be conflicts between different customers.

Thanks Sekhar
