description:
- Manages BFD global configuration on HUAWEI CloudEngine devices.
author: QijunPan (@CloudEngine-Ansible)
options:
bfd_enable:
description:
- Enables the global Bidirectional Forwarding Detection (BFD) function.
choices: ['enable', 'disable']
default_ip:
description:
- Specifies the default multicast IP address.
The value ranges from 224.0.0.107 to 224.0.0.250.
tos_exp_dynamic:
description:
- Indicates the priority of BFD control packets for dynamic BFD sessions.
The value is an integer ranging from 0 to 7.
The default priority is 7, which is the highest priority of BFD control packets.
tos_exp_static:
description:
- Indicates the priority of BFD control packets for static BFD sessions.
The value is an integer ranging from 0 to 7.
The default priority is 7, which is the highest priority of BFD control packets.
damp_init_wait_time:
description:
- Specifies an initial flapping suppression time for a BFD session.
The value is an integer ranging from 1 to 3600000, in milliseconds.
The default value is 2000.
damp_max_wait_time:
description:
- Specifies a maximum flapping suppression time for a BFD session.
The value is an integer ranging from 1 to 3600000, in milliseconds.
The default value is 15000.
damp_second_wait_time:
description:
- Specifies a secondary flapping suppression time for a BFD session.
The value is an integer ranging from 1 to 3600000, in milliseconds.
The default value is 5000.
delay_up_time:
description:
- Specifies the delay before a BFD session becomes Up.
The value is an integer ranging from 1 to 600, in seconds.
The default value is 0, indicating that a BFD session immediately becomes Up.
state:
description:
- Determines whether the config should be present or not on the device.
default: present
choices: ['present', 'absent']
