What about those Routes I see in the Network console?
GCP Networking uses Routes to direct packets between subnetworks and to the Internet.
Whenever a subnetwork is created (or pre-created) in your Network, routes are automatically created in each region to allow packets to route between subnetworks. These cannot be modified.
Additional routes can be created to send traffic to an instance, a VPN gateway, or default internet gateway. These can be modified to tailor the desired network architecture.
Routes and Firewalls work together to ensure your traffic gets where it needs to go.
