## Synopsis

- Manages BFD session configuration, creates a BFD session or deletes a specified BFD session on HUAWEI CloudEngine devices.

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
addr_type - | Choices: ipv4 | Specifies the peer IP address type.
create_type - | Choices: static ← auto | BFD session creation mode, the currently created BFD session only supports static or static auto-negotiation mode.
dest_addr - |  | Specifies the peer IP address bound to the BFD session.
local_discr - added in 2.9 |  | The BFD session local identifier does not need to be configured when the mode is auto.
out_if_name - |  | Specifies the type and number of the interface bound to the BFD session.
remote_discr - added in 2.9 |  | The BFD session remote identifier does not need to be configured when the mode is auto.
session_name - / required |  | Specifies the name of a BFD session. The value is a string of 1 to 15 case-sensitive characters without spaces.
src_addr - |  | Indicates the source IP address carried in BFD packets.
state - | Choices: present ← absent | Determines whether the config should be present or not on the device.
use_default_ip boolean | Choices: no ← yes | Indicates the default multicast IP address that is bound to a BFD session. By default, BFD uses the multicast IP address 224.0.0.184. You can set the multicast IP address by running the default-ip-address command. The value is a bool type.
vrf_name - |  | Specifies the name of a Virtual Private Network (VPN) instance that is bound to a BFD session. The value is a string of 1 to 31 case-sensitive characters, spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string. The value _public_ is reserved and cannot be used as the VPN instance name.

## Notes

Note

- This module requires the netconf system service be enabled on the remote device being managed.

- Recommended connection is `netconf`.

- This module also works with `local` connections for legacy playbooks.
