## Synopsis

- Manages tunnels on a BIG-IP. Tunnels are usually based upon a tunnel profile which defines both default arguments and constraints for the tunnel.

- Due to this, this module exposes a number of settings that may or may not be related to the type of tunnel you are working with. It is important that you take this into consideration when declaring your tunnel config.

- If a specific tunnel does not support the parameter you are considering, the documentation of the parameter will usually make mention of this. Otherwise, when configuring that parameter on the device, the device will notify you.

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
auto_last_hop string | Choices: default enabled disabled | Allows you to configure auto last hop on a per-tunnel basis. When creating a new tunnel, if this parameter is supported by the tunnel profile but not specified, the default is `default`. When `default`, means that the system uses the global auto-lasthop setting to send back the request. When `enabled`, allows the system to send return traffic to the MAC address that transmitted the request, even if the routing table points to a different network or interface. As a result, the system can send return traffic to clients even when there is no matching route.
description string |  | Description of the tunnel.
key integer |  | When applied to a GRE tunnel, this value specifies an optional field in the GRE header, used to authenticate the source of the packet. When applied to a VXLAN or Geneve tunnel, this value specifies the Virtual Network Identifier (VNI). When applied to an NVGRE tunnel, this value specifies the Virtual Subnet Identifier (VSID). When creating a new tunnel, if this parameter is supported by the tunnel profile but not specified, the default value is `0`.
local_address string |  | Specifies the IP address of the local endpoint of the tunnel.
mode string | Choices: bidirectional inbound outbound | Specifies how the tunnel carries traffic. When creating a new tunnel, if this parameter is supported by the tunnel profile but not specified, the default is `bidirectional`. When `bidirectional`, specifies that the tunnel carries both inbound and outbound traffic. When `inbound`, specifies that the tunnel carries only incoming traffic. When `outbound`, specifies that the tunnel carries only outgoing traffic.
mtu integer |  | Specifies the maximum transmission unit (MTU) of the tunnel. When creating a new tunnel, if this parameter is supported by the tunnel profile but not specified, the default value is `0`. The valid range is from `0` to `65515`.
name string / required |  | Specifies the name of the tunnel.
partition string | Default: "Common" | Device partition to manage resources on.
profile string |  | Specifies the profile to associate with the tunnel for handling traffic. Depending on your selection, other settings become available or disappear. This parameter may not be changed after it is set.
provider dictionary added in 2.5 |  | 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.
| password 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`. aliases: pass, pwd
| server string / required |  | The BIG-IP host. You may omit this option by setting the environment variable `F5_SERVER`.
| server_port integer | Default: 443 | The BIG-IP server port. You may omit this option by setting the environment variable `F5_SERVER_PORT`.
| ssh_keyfile path |  | Specifies the SSH keyfile to use to authenticate the connection to the remote device. This argument is only used for cli transports. You may omit this option by setting the environment variable `ANSIBLE_NET_SSH_KEYFILE`.
| 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 | Choices: cli rest ← | Configures the transport connection to use when connecting to the remote device.
| 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 | Choices: no yes ← | 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`.
remote_address string |  | Specifies the IP address of the remote endpoint of the tunnel. For `dslite`, `fec` (when configuring the FEC tunnel for receiving traffic only), `v6rd` (configured as a border relay), or `map`, the tunnel must have an unspecified remote address (any).
secondary_address string |  | Specifies a non-floating IP address for the tunnel, to be used with host-initiated traffic.
state string | Choices: present ← absent | When `present`, ensures that the tunnel exists. When `absent`, ensures the tunnel is removed.
tos string |  | Specifies the Type of Service (TOS) value to insert in the encapsulating header of transmitted packets. When creating a new tunnel, if this parameter is supported by the tunnel profile but not specified, the default value is `preserve`. When `preserve`, the system copies the TOS value from the inner header to the outer header. You may also specify a numeric value. The possible values are from `0` to `255`.
traffic_group string |  | Specifies the traffic group to associate with the tunnel. This value cannot be changed after it is set. This is a limitation of BIG-IP.
transparent boolean | Choices: no yes | Specifies that the tunnel operates in transparent mode. When `yes`, you can inspect and manipulate the encapsulated traffic flowing through the BIG-IP system. A transparent tunnel terminates a tunnel while presenting the illusion that the tunnel transits the device unmodified (that is, the BIG-IP system appears as if it were an intermediate router that simply routes IP traffic through the device).
use_pmtu boolean | Choices: no yes | Enables or disables the tunnel to use the PMTU (Path MTU) information provided by ICMP NeedFrag error messages. If `yes` and the tunnel `mtu` is set to `0`, the tunnel will use the PMTU information. If `yes` and the tunnel `mtu` is fixed to a non-zero value, the tunnel will use the minimum of PMTU and MTU. If `no`, the tunnel will use fixed MTU or calculate its MTU using tunnel encapsulation configurations.

## 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 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.

## Examples

    - name: Create a VXLAN tunnel
      bigip_tunnel:
        name: openshift-tunnel
        local_address: 192.1681.240
        key: 0
        secondary_address: 192.168.1.100
        mtu: 0
        use_pmtu: yes
        tos: preserve
        auto_last_hop: default
        traffic_group: traffic-group-1
        state: present
        provider:
          password: secret
          server: lb.mydomain.com
          user: admin
      delegate_to: localhost

## Return Values

Common return values are documented here, the following are the fields unique to this module:

Key | Returned | Description
--- | --- | ---
param1 boolean | changed | The new param1 value of the resource. Sample: True
param2 string | changed | The new param2 value of the resource. Sample: Foo is bar

## Status

- This module is not guaranteed to have a backwards compatible interface. [preview]

- This module is maintained by an Ansible Partner. [certified]
