Requirements

The below requirements are needed on the host that executes this module.

  • ncclient (>=v0.6.4)

  • xmltodict (>=0.12.0)

Parameters

Parameter

Comments

config

list / elements=dictionary

The provided link BGP address family dictionary.

address_prefixes

list / elements=string

Specify address prefixes.

dynamic_db

boolean

Enable object to exist in dynamic DB.

Choices:

  • no

  • yes

name

string / required

Specify the name of the prefix-list.

running_config

string

This option is used only with state parsed.

The value of this option should be the output received from the Junos device by executing the command show policy-options.

The state parsed reads the configuration from running_config option and transforms it into Ansible structured data as per the resource module’s argspec and the value is then returned in the parsed key within the result

state

string

The state the configuration should be left in.

Choices:

  • merged ← (default)

  • replaced

  • overridden

  • deleted

  • parsed

  • gathered

  • rendered

Notes

Note

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

  • This module works with connection netconf.

  • See the Junos OS Platform Options.

  • Tested against JunOS v18.4R1
