+The new fields MUST be supported by the already existing endpoints to create and update and get
+routes:
+* [`POST /v3/routes`](https://v3-apidocs.cloudfoundry.org/version/3.159.0/index.html#create-a-route)
+* [`GET /v3/routes/:guid`](https://v3-apidocs.cloudfoundry.org/version/3.159.0/index.html#get-a-route)
+* [`GET /v3/routes`](https://v3-apidocs.cloudfoundry.org/version/3.159.0/index.html#list-routes)
+* [`GET /v3/apps/:guid/routes`](https://v3-apidocs.cloudfoundry.org/version/3.159.0/index.html#list-routes-for-an-app)
+* [`PATCH /v3/routes/:guid`](https://v3-apidocs.cloudfoundry.org/version/3.159.0/index.html#update-a-route)
+
 Implementation details:
 * Add a new field to the [route model](https://github.com/cloudfoundry/cloud_controller_ng/blob/main/app/models/runtime/route.rb).
 * Add validation to the [route validator](https://github.com/cloudfoundry/cloud_controller_ng/blob/e719d017ea4625397a97c2c14352ebdee66febe9/lib/cloud_controller/route_validator.rb#L2).
+* Use a mechanism similar to the [droplet](https://github.com/cloudfoundry/cloud_controller_ng/blob/e719d017ea4625397a97c2c14352ebdee66febe9/app/models/runtime/droplet_model.rb#L47-L48) to store the encoded map.
