Class:NsNetwork

Derived from Class:NsVirtualLink.

Implement the openstack subnetwork/network model.

Attribute

Qualifier

Cardinality

Content

Description

state

cidr

M

1

String

The CIDR of the subnet.

allocationPools

M

0..N

KeyValue

Allocation pools with start and end IP addresses for this subnet. If allocation_pools are not specified, OpenStack Networking automatically allocates pools for covering all IP addresses in the CIDR, excluding the address reserved for the subnet gateway by default.

gatewayIp

M

0..1

String

Gateway IP of this subnet. If the value is null that implies no gateway is associated with the subnet. If the gateway_ip is not specified, OpenStack Networking allocates an address from the CIDR for the gateway for the subnet by default.

dhcpEnabled

M

0..1

Boolean

Indicates whether dhcp is enabled or disabled for the subnet. Default is true.

NetworkName M 1 String Human-readable name of the network

networkId M 0..1 String The network id that represents an existing Network instance in the underlying cloud infrastructure.

segmentationId

M

0..1

String

The ID of the isolated segment on the physical network. The network_typeattribute defines the segmentation model. For example, if the network_type value is vlan, this ID is a vlan identifier. If the network_type value is gre, this ID is a gre key.

networkType

M

0..1

Enum

The type of physical network that this network should be mapped to. For example, flat, vlan, vxlan, or gre. Valid values depend on a networking back-end.

physicalNetwork

M

0..1

String

The physical network where this network should be implemented. The Networking API v2.0 does not provide a way to list available physical networks. For example, the Open vSwitch plug-in configuration file defines a symbolic name that maps to specific bridges on each compute host

vlanTransparent

M

0..1

Boolean

Indicates the VLAN transparency mode of the network, which is VLAN transparent (true) or not VLAN transparent (false)

Class: Vnfd

refer to resource definition

Class: VnfExtCp

refer to resource definition

In R2, VnfExtCp refers to the VduCP exposed from the VNF via substitution mapping.
