Implementing a global transit network architecture using VWAN
One of the advantages of implementing Azure VWAN for connectivity is its support for an “out-of-the-box” global transit network architecture. This is because it allows any-to-any connectivity between all connections to VWAN (branches, VNets, and users)! This removes or reduces the need for full mesh or partial mesh connectivity between multiple networks.

For example, in the scenario highlighted in Figure 7.49, VWAN supports the following global transit connectivity paths without the need for any additional routing configuration:
- Branch to VNet
- Branch to branch
- Remote user to VNet
- Remote user to branch
- VNet to VNet
- Branch-to-hub-to-hub-to-Branch
- Branch-to-hub-to-hub-to-VNet
- VNet-to-hub-to-hub-to-VNet
