Overview
IMC Orchestrator supports the hybrid overlay scenario of interoperating with native OpenStack. The
scenario mainly implements the hybrid traffic model containing weak-control EVPN network overlay
and strong-control host overlay. OpenStack provides rich versions. This configuration guide uses the
Rocky version as an example to describe the passthrough and secure incorporation network
scenario models.

Configure basic OpenStack settings
Before performing configuration tasks in this chapter, first install the HPE IMC Orchestrator
OpenStack plug-in in OpenStack to enable the controller to interoperate with OpenStack. For how
to install the HPE IMC Orchestrator OpenStack plug-in, see HPE IMC Orchestrator Converged
OpenStack Plug-Ins Installation Guide.
NOTE:
If the IMC Orchestrator controller has interoperated with a non-converged OpenStack plug-in, you
must configure parameters according to the configuration items for a non-converged plug-in. For
more information, see the chapter about upgrading non-converged plug-ins to converged plug-ins
in HPE IMC Orchestrator Converged OpenStack Plug-Ins Installation Guide.
Perform the following tasks when OpenStack interoperates with the controller for the first time.
Add OpenStack nodes on the controller
1. Navigate to the Automation > Data Center Networks > Virtual Networking > OpenStack
page. Click Add. The page for adding an OpenStack control node opens, as shown in Figure
10.
Configure the parameters as follows:
ï‚¡ After adding a node, you cannot modify its name, and the node name must be the same
as the value for the cloud_region_name field in the plug-in configuration file
/etc/neutron/plugins/ml2/ml2_conf.ini.
ï‚¡ The VNI range must be the same as the value for the vni_ranges field in the
/etc/neutron/plugins/ml2/ml2_conf.ini file. The VNI ranges for different OpenStack
nodes cannot overlap.
ï‚¡ If the controller nodes operate in HA mode, you must add the addresses of all controller
nodes rather than only the cluster VIP. If the keystone service is shared, you must add two
OpenStack nodes.
ï‚¡ You must install the websocket-client toolkit on the controller nodes.
Figure 10 Adding OpenStack nodes on the controller side
2. Click the Parameter Settings tab. Configure parameters. For how to configure these
parameters, see the controller help or HPE IMC Orchestrator Converged OpenStack Plug-Ins
Installation Guide.

Figure 11 OpenStack parameter settings
NOTE:
• When the tenant border gateway policy is configured as matching the border gateway
name in the egress settings, you must enter the border gateway name correctly.
• In the network fail-open scenario, you must enable the DHCP agent, and as a best
practice, configure the network node access policy as No Access.
• When the network node access policy is configured as VLAN, the DHCP-type vPorts will
be activated on the controller (come online in hierarchical mode), and the packets will be
encapsulated as VLAN packets when they are sent out of network nodes. When the
network node access policy is configured as VXLAN, the DHCP-type vPorts are not
activated on the controller, and the packets are encapsulated as VXLAN packets when
they are sent out of the network nodes. When a network node accesses a DR system,
only the VLAN mode is supported.
• If a network node can act as a DHCP server in the network, you must disable the function
of sending DHCP packets to the controller in the vNetwork settings on the controller side.
As a best practice, use the controller as the DHCP server (enable the function of sending
DHCP packets to the controller).
Configure the default VDS and VXLAN pool
This task is required only for interoperating with the controller for the first time.
In the current software version, only one VDS is supported.
To configure the default VDS and VXLAN pool:
1. Navigate to the Automation > Data Center Networks > Common Network Settings >
Virtual Distributed Switch page. Click Settings. In the dialog box that opens, select the
system VDS.

2. Navigate to the Automation > Data Center Networks > Resource Pools > VNID Pools >
VXLANs page. Click Add. The page for adding VXLANs opens. Add a VXLAN pool.
Figure 13 Configuring VXLAN pools
NOTE:
Create a VXLAN pool for uniformly managing the L3VNI segments of user vRouters.
Configure the default cloud platform
This task is required only when OpenStack interoperates with the controller for the non-first time and
the previous plug-in configuration items do not have the multi-cloud attribute.
To configure the default cloud platform:
1. Navigate to the Automation > Data Center Networks > Virtual Networking > OpenStack
page. Click Default Cloud Platform. In the dialog box that opens, select the default cloud
platform.

Configure a hybrid overlay network
The campus access devices do not support bare metal access.
Network planning
Network topology
Figure 15 OpenStack hybrid overlay network diagram
A hybrid overlay network includes a host overlay network and network overlay network. The ARP
proxy function is not supported on the host overlay side. The LB VIP and members cannot be on the
same subnet. The client and VIP cannot be on the same subnet.
On a host overlay network, the vSwitches on OpenStack compute nodes act as VTEPs and establish
VXLAN tunnels to other VTEPs for forwarding VXLAN packets. On a host overlay network, you need
the vBGP component to provide the IBGP routing function. The vBGP component is deployed on the
IMC PLAT server. The IMC PLAT server is connected to the management switch through an
aggregate interface, and the management switch is connected to Spine1 and Spine2. An IBGP
neighbor is established between the vBGP component and RR to synchronize route information.
On a network overlay network, leaf switches act as VTEPs and establish VXLAN tunnels to other
VTEPs, and the vSwitches on OpenStack compute nodes do not act as VTEPs or provide VXLAN
packet forwarding. The network overlay includes hierarchical onboarding and non-hierarchical
onboarding scenarios. In the non-hierarchical onboarding scenario, the controller deploys VXLAN
configuration to leaf devices based on VLAN-VXLAN mappings. In the hierarchical onboarding

Deployment workflow
Figure 16 Deployment workflow
Among the vBGP, host overlay, and network overlay configurations, if you only need to configure
OpenStack+network overlay, you can skip the vBGP and host overlay configuration procedures. If
you only need to configure OpenStack+host overlay, you can skip the network overlay configuration
procedure.
When you configure the network with direct egress and the network with security egress, configure
the network according to the actual network conditions.
Procedure
Configure vBGP
You must configure vBGP for the hybrid overlay network. You do not need to configure vBGP for the
network overlay network.
