Peering and VNet-to-VNet connections can be used together to enable all networks to see each other.

The Allow Gateway Transit must be turned on for these packets to be leveraged.

This is very interesting because I can connect two VNETs in the same region and establish a VPN between one of them and a third one in a different region to establish connection between them all.
