Synopsis

  • Manages GTM (now BIG-IP DNS) Topology Records. Once created, only topology record weight can be modified.

Parameters

Parameter

Comments

destination

dictionary / required

Specifies where the system directs the incoming DNS request.

continent

string

Specifies one of the seven continents, along with the Unknown setting.

Specifying Unknown forces the system to use a default resolution if the system cannot determine the location of the local DNS making the request.

Full continent names and their abbreviated versions are supported.

country

string

Specifies a country.

Full continent names and their abbreviated versions are supported.

datacenter

string

Specifies the name of GTM data center already defined in the configuration.

geo_isp

string

Specifies a geolocation ISP

isp

string

Specifies an Internet service provider.

Choices:

  • "AOL"

  • "BeijingCNC"

  • "CNC"

  • "ChinaEducationNetwork"

  • "ChinaMobilNetwork"

  • "ChinaRailwayTelcom"

  • "ChinaTelecom"

  • "ChinaUnicom"

  • "Comcast"

  • "Earthlink"

  • "ShanghaiCNC"

  • "ShanghaiTelecom"

negate

boolean

When set to yes the system selects this topology record, when the request destination does not match.

Choices:

  • false ← (default)

  • true

pool

string

Specifies the name of GTM pool already defined in the configuration.

region

string

Specifies the name of region already defined in the configuration.

state

string

Specifies a state in a given country.

This parameter requires the country option.

subnet

string

An IP address and network mask in the CIDR format.

partition

string

Device partition to manage resources on.

Partition parameter is taken into account when used in conjunction with pool, data_center, and region parameters, otherwise it is ignored.

Default: "Common"

provider

dictionary

added in f5networks.f5_modules 1.0.0

A dict object containing connection details.

auth_provider

string

Configures the auth provider for to obtain authentication tokens from the remote device.

This option is really used when working with BIG-IQ devices.

no_f5_teem

boolean

If yes, TEEM telemetry data is not sent to F5.

You may omit this option by setting the environment variable F5_TELEMETRY_OFF.

Previously used variable F5_TEEM is deprecated as its name was confusing.

Choices:

  • false ← (default)

  • true

password

aliases: pass, pwd

string / required

The password for the user account used to connect to the BIG-IP.

You may omit this option by setting the environment variable F5_PASSWORD.

server

string / required

The BIG-IP host.

You may omit this option by setting the environment variable F5_SERVER.

server_port

integer

The BIG-IP server port.

You may omit this option by setting the environment variable F5_SERVER_PORT.

Default: 443

timeout

integer

Specifies the timeout in seconds for communicating with the network device for either connecting or sending commands. If the timeout is exceeded before the operation is completed, the module will error.

transport

string

Configures the transport connection to use when connecting to the remote device.

Choices:

  • "rest" ← (default)

user

string / required

The username to connect to the BIG-IP with. This user must have administrative privileges on the device.

You may omit this option by setting the environment variable F5_USER.

validate_certs

boolean

If no, SSL certificates are not validated. Use this only on personally controlled sites using self-signed certificates.

You may omit this option by setting the environment variable F5_VALIDATE_CERTS.

Choices:

  • false

  • true ← (default)

source

dictionary / required

Specifies the origination of an incoming DNS request.

continent

string

Specifies one of the seven continents, along with the Unknown setting.

Specifying Unknown forces the system to use a default resolution if the system cannot determine the location of the local DNS making the request.

Full continent names and their abbreviated versions are supported.

country

string

Specifies a country.

In addition to the country full names, you may also specify their abbreviated form, such as US instead of United States.

Valid country codes can be found here https://countrycode.org/.

geo_isp

string

Specifies a geolocation ISP.

isp

string

Specifies an Internet service provider.

Choices:

  • "AOL"

  • "BeijingCNC"

  • "CNC"

  • "ChinaEducationNetwork"

  • "ChinaMobilNetwork"

  • "ChinaRailwayTelcom"

  • "ChinaTelecom"

  • "ChinaUnicom"

  • "Comcast"

  • "Earthlink"

  • "ShanghaiCNC"

  • "ShanghaiTelecom"

negate

boolean

When set to c(yes) the system selects this topology record, when the request source does not match.

Choices:

  • false ← (default)

  • true

region

string

Specifies the name of region already defined in the configuration.

state

string

Specifies a state in a given country.

This parameter requires the country option.

subnet

string

An IP address and network mask in the CIDR format.

state

string

When state is present, ensures the record exists.

When state is absent, ensures the record is removed.

Choices:

  • "present" ← (default)

  • "absent"

weight

integer

Specifies the weight of the topology record.

The system finds the weight of the first topology record that matches the server object (pool or pool member) and the local DNS. The system then assigns that weight as the topology score for that server object.

The system load balances to the server object with the highest topology score.

If the system finds no topology record that matches both the server object and the local DNS, then the system assigns that server object a zero score.

If the option is not specified when the record is created the system will set it at a default value of 1

Valid range is (0 - 4294967295)

Notes

Note

  • For more information on using Ansible to manage F5 Networks devices see https://www.ansible.com/integrations/networks/f5.

  • Requires BIG-IP software version >= 12.

  • The F5 modules only manipulate the running configuration of the F5 product. To ensure that BIG-IP specific configuration persists to disk, be sure to include at least one task that uses the f5networks.f5_modules.bigip_config module to save the running configuration. Refer to the module’s documentation for the correct usage of the module to save your running configuration.
