Routes-based cluster

As explained in Google Anthos in Action

A routes-based cluster is a GKE cluster whose pod networking relies on Google Cloud routes rather than native VPC pod addresses.

A routes-based cluster is an Anthos GKE on Google Cloud deployment that relies on Google Cloud routes for Pod networking, rather than assigning Pods native VPC addresses. It is an alternative to the default, recommended VPC-native cluster. section 10.2.1

The deployment trade-off is route management. VPC-native clusters use secondary IP ranges and automatically generated subnet routes instead of custom static routes for Pod ranges, avoiding consumption of the static-route quota. Account for that distinction when choosing a cluster networking model. section 10.2.1

How Google Anthos in Action covers it

How deep it goes
Defines the option through its contrast with VPC-native routing, without providing routes-based configuration steps.
Examples
Uses VPC-native Pod connectivity to other VPC entities as a contrasting deployment example.
What you can do after
Evaluate/understand the route-management distinction when comparing GKE cluster networking options.
How it connects
Connects routes-based clusters to VPC-native clusters, Pod IP ranges, subnet routes, and static-route quotas.
