short_description: Manages PIM interface configuration.

description:

|
- Manages PIM interface configuration settings.
|
|
author:
|
|
- Jason Edelman (@jedelman8)
|
|
notes:
|
|
- Tested against NXOSv 7.3.(0)D1(1) on VIRL
|
|
- When C(state=default), supported params will be reset to a default state.
|
|
These include C(dr_prio), C(hello_auth_key), C(hello_interval), C(jp_policy_out),
|
|
C(jp_policy_in), C(jp_type_in), C(jp_type_out), C(border), C(neighbor_policy),
|
|
C(neighbor_type).
|
|
- The C(hello_auth_key) param is not idempotent.
|
|
- C(hello_auth_key) only supports clear text passwords.
|
|
- When C(state=absent), pim interface configuration will be set to defaults and pim-sm
|
|
will be disabled on the interface.
|
|
- PIM must be enabled on the device to use this module.
|
|
- This module is for Layer 3 interfaces.
