module: bigip_management_route
short_description: Manage system management routes on a BIG-IP
description:
- Configures route settings for the management interface of a BIG-IP.
version_added: 2.6
options:
name:
description:
- Specifies the name of the management route.
required: True
description:
description:
- Description of the management route.
gateway:
description:
- Specifies that the system forwards packets to the destination through the
gateway with the specified IP address.
network:
description:
- The subnet and netmask to be used for the route.
- To specify that the route is the default route for the system, provide the
value C(default).
- Only one C(default) entry is allowed.
- This parameter cannot be changed after it is set. Therefore, if you do need to change
it, it is required that you delete and create a new route.
partition:
description:
- Device partition to manage resources on.
default: Common
state:
description:
- When C(present), ensures that the resource exists.
- When C(absent), ensures the resource is removed.
default: present
choices:
- present
- absent
