module: junos_vrf
version_added: "2.4"
author: "Ganesh Nalawade (@ganeshrn)"
short_description: Manage the VRF definitions on Juniper JUNOS devices
description:
- This module provides declarative management of VRF definitions on
Juniper JUNOS devices. It allows playbooks to manage individual or
the entire VRF collection.
options:
name:
description:
- The name of the VRF definition to be managed on the remote IOS
device. The VRF definition name is an ASCII string name used
to uniquely identify the VRF. This argument is mutually exclusive
with the C(aggregate) argument
description:
description:
- Provides a short description of the VRF definition in the
current active configuration. The VRF definition value accepts
alphanumeric characters used to provide additional information
about the VRF.
rd:
description:
- The router-distinguisher value uniquely identifies the VRF to
routing processes on the remote IOS system. The RD value takes
the form of C(A:B) where C(A) and C(B) are both numeric values.
interfaces:
description:
- Identifies the set of interfaces that
should be configured in the VRF. Interfaces must be routed
interfaces in order to be placed into a VRF.
target:
description:
- It configures VRF target community configuration. The target value takes
the form of C(target:A:B) where C(A) and C(B) are both numeric values.
table_label:
description:
- Causes JUNOS to allocate a VPN label per VRF rather than per VPN FEC.
This allows for forwarding of traffic to directly connected subnets, COS
Egress filtering etc.
aggregate:
description:
- The set of VRF definition objects to be configured on the remote
JUNOS device. Ths list entries can either be the VRF name or a hash
of VRF definitions and attributes. This argument is mutually
exclusive with the C(name) argument.
state:
description:
- Configures the state of the VRF definition
as it relates to the device operational configuration. When set
to I(present), the VRF should be configured in the device active
configuration and when set to I(absent) the VRF should not be
in the device active configuration
default: present
choices: ['present', 'absent']
active:
description:
- Specifies whether or not the configuration is active or deactivated
default: True
choices: [True, False]
requirements:
- ncclient (>=v0.5.2)
notes:
- This module requires the netconf system service be enabled on
the remote device being managed.
- Tested against vSRX JUNOS version 15.1X49-D15.4, vqfx-10000 JUNOS Version 15.1X53-D60.4.
