module: gcp_compute_route_info
description:
- Gather info for GCP Route
- This module was called C(gcp_compute_route_facts) before Ansible 2.9. The usage
  has not changed.
short_description: Gather info for GCP Route
version_added: 2.7
author: Google Inc. (@googlecloudplatform)
requirements:
- python >= 2.6
- requests >= 2.18.4
- google-auth >= 1.3.0
options:
  filters:
    description:
    - A list of filter value pairs. Available filters are listed here U(https://cloud.google.com/sdk/gcloud/reference/topic/filters).
    - Each additional filter in the list will act be added as an AND condition (filter1
      and filter2) .
    type: list

- name: get info on a route

    name:
      description:
      - Name of the resource. Provided by the client when the resource is created.
        The name must be 1-63 characters long, and comply with RFC1035. Specifically,
        the name must be 1-63 characters long and match the regular expression `[a-z]([-a-z0-9]*[a-z0-9])?`

      description:
      - The priority of this route. Priority is used to break ties in cases where
        there is more than one matching route of equal prefix length.
      - In the case of two routes with equal prefix length, the one with the lowest-numbered
        priority value wins.
      - Default value is 1000. Valid range is 0 through 65535.
