For VMware Integrated OpenStack deployments based on NSX, the API access, Management, Transport, and External network each require a separate and dedicated VLAN.

Request that your network administrator prepare the necessary VLANs.

VLAN

Description

API Access network

Provides access for users to the OpenStack services through APIs or the VMware Integrated OpenStack dashboard.

Trunk all hosts in the Management cluster to this VLAN.

Make externally accessible.

Requires five or more continuous IP addresses.

Management network

Carries traffic among the management components.

Trunk all hosts in the Management cluster to this VLAN.

Trunk all hosts in the Compute cluster to this VLAN.

Requires 18 or more continuous IP addresses. (21 if you add the Ceilometer component.)

Enable L2 or L3 access to this VLAN for the following components:

vCenter server

NSX Manager

NSX Controller

If you are deploying the NSX Manager and NSX Controller VMs on the Management cluster, you must trunk their hosts to the Management network.

Transport

Carries traffic among the OpenStack instances.

Trunk all hosts in the Compute cluster to this VLAN.

Trunk all hosts in the NSX Edge cluster to this VLAN.

Important

The Maximum Transmission Unit (MTU) settings for the Transport VLAN must be configured to support 1600 bytes. See the Knowledge Base at http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2093324.

External

Provides external user access to the instances.

Trunk all hosts in the NSX Edge cluster to this VLAN.
