| flowPattern | String | 0..1 | Identifies the flow pattern of the connectivity (Line, Tree, Mesh). | support: MANDATORY |
Class: VirtualLinkDf
Attribute Name | Type | Multiplicity | Description | Applied Stereotypes |
|---|---|---|---|---|

Class:OpenstackNetwork
Derived from Class:NsVirtualLink.
Implement the openstack subnetwork/network model.
Attribute | Qualifier | Cardinality | Content | Description | Producer | Consumer |
cidr | M | 1 | String | The CIDR of the subnet. | SDC | SDC/UUI/VFC |
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. | SDC | SDC/UUI/VFC |
