What is Virtual Network Peering?

Virtual Network Peering allows you to connect to different virtual networks in the same or different regions.
There are two types of VNet Peerings:
- Regional virtual network peering: Connect Virtual Networks in the same region.
- Global virtual network peering:Connect Virtual Networks in different regions.
Azure Virtual Network Peering offers private network connections ensuring secure transfers.
Traffic between the VMs in the Virtual Networks are routed via the Microsoft Backbone Architecture.
Azure VPN Gateway can be configured in the peered Virtual Networks as a transit point.
A minimum of two Virtual Networks are required for peering.
The second virtual network in the peering is referred to as the remote network.
The Virtual Network Peering is considered to be successful when the status is Connected

Overlapping CIDR Blocks

Two virtual networks with overlapping CIDR blocks cannot be directly peered.
