You can create provider and external networks for your VMware Integrated OpenStack deployment, configure availability zones, and perform other advanced networking tasks.

Create a Provider Network
Provider networks map to physical networks in your data center, and their networking functions are performed by physical devices.
Create an External Network
External networks act as floating IP address pools to provide external access for instances in your deployment.
Create a Layer 2 Bridge
A Layer 2 bridge allows compute nodes on an overlay network to communicate with a physical VLAN.
Create a Neutron Availability Zone
Neutron availability zones enable high availability for network resources. You can place nodes running the same service in different availability zones to ensure that service is not interrupted in the event of a failure in one zone.
Configure VMware Integrated OpenStack with an NSX Manager Cluster
NSX-T Data Center 2.4 and later support the deployment of multiple NSX Manager nodes to form a cluster in a single NSX-T Data Center instance. If you want to use an NSX Manager cluster with VMware Integrated OpenStack, add the IP addresses of all cluster nodes to your deployment configuration.
Use NSX-T Data Center N-VDS Enhanced Data Path Mode with OpenStack
For NSX-T Data Center deployments, you can create networks and ports backed by a transport zone using N-VDS enhanced data path mode.
Configure VLAN Transparency
VLAN-transparent networks allow tagged packets to pass through without tags being removed or changed.
Configure MAC Learning
MAC learning enables network connectivity for multiple MAC addresses behind a single vNIC. MAC learning is useful for distributing workloads in large OpenStack deployments.
Manage Edge HA with NSX Data Center for vSphere
For NSX Data Center for vSphere deployments, you can enable HA for NSX Edge nodes and specify host groups in which the nodes will be placed.
Specify Tenant Router Types for NSX Data Center for vSphere
For NSX Data Center for vSphere deployments, you can restrict the router types available to tenants and specify a default router type.
Configure Dynamic Routing for Neutron Networks with NSX Data Center for vSphere
You can configure BGP dynamic routing for the provider and tenant networks in your environment.
Add an NSX-T Data Center Back End to an NSX Data Center for vSphere Deployment
If you have deployed VMware Integrated OpenStack with NSX Data Center for vSphere, you can specify an NSX-T Data Center back end for certain projects in your deployment.
Create a Provider Security Group
You can create a provider security group to block specific traffic for a project.
Use NSX Data Center for vSphere Security Policies in OpenStack
You can enforce NSX Data Center for vSphere security policies through Neutron security groups. This feature can also be used to insert third-party network services.
