Create Single Segment Virtio VM Network

About this task

Perform this procedure to create a single segment Virtio VM network on default physnet and extend the network to DC Edge.

Note

VLAN provisioning depends on the following:

Neutron Virtio ports are bound to a host during VM launch
DHCP ports are bound during subnet creation
DC Edge extension is achieved using explicit port-create

The following figure shows an overview of a single segment Virtio VM Network with DC Edge.

Procedure

Create an OpenStack network on default physnet.
```
# openstack network create --provider-network-type vlan --provider-physical-network default --provider-segment 3320 ss1network1
```
EPG is created for ss1network:
- Name: 74cbf489-f3d9-41c7-bbb2-6cb7df33da6d
- CTAG: 3320
- Neutron UUID allocated for the EPG: 74cbf489-f3d9-41c7-bbb2-6cb7df33da6d

Create DHCP End Points on EPG corresponding to ss1network1.

# openstack subnet create ss1subnet1 --network ss1network1 --subnet-range 10.1.1.0/24

VLAN is provisioned.

Update EPG.

# openstack subnet create ss1subnet1ipv6 --network ss1network1 --ip-version 6 --ipv6-address-mode=dhcpv6-stateful --subnet-range fd00:10:0:57::1000/64

EPG is updated and port lag_1 is added.

Create OpenStack ports and network trunk.

# openstack port create ss1VirtIoTrunkPort1 --network ss1network1

#openstack network trunk create --parent-port ss1VirtIoTrunkPort1 ss1VirtIoTrunk1

# openstack port create ss1VirtIoSubport1 --network ss1network1

Create EPG for SS1network2.

# openstack network create --provider-network-type vlan --provider-physical-network default --provider-segment 3321 ss1network2

EPG is created for ss1network2:

Name: 84cbf489-f3d9-41c7-bbb2-6cb7df33da6d
CTAG: 3321

Create DHCP End Points on EPG corresponding to ss1network2.

# openstack subnet create ss1subnet2 --network ss1network2 --subnet-range 11.1.1.0/24

VLAN is provisioned.

Update EPG.

# openstack subnet create ss1subnet2ipv6 --network ss1network2 --ip-version 6 --ipv6-address-mode=dhcpv6-stateful --subnet-range fd00:11:0:57::1000/64

EPG is updated:

Name: 84cbf489-f3d9-41c7-bbb2-6cb7df33da6d
Port: lag_1 (added)

Create an OpenStack port.

# openstack port create ss1VirtIoTrunkPort2 --network ss1network2

Create an OpenStack network trunk.

# openstack network trunk create --parent-port ss1VirtIoTrunkPort2 ss1VirtIoTrunk2

Create an OpenStack network trunk set.

# openstack network trunk set --subport port=ss1VirtIoSubport1,segmentation-type=vlan,segmentation-id=3801 ss1VirtIoTrunk2

Create an OpenStack server.
```
# openstack server create --flavor m1.large --image ubuntu --port $(neutron port-list | grep -w 'ss1VirtIoTrunkPort1' | awk '{print $2}') ss1VirtIoVM1 --availability-zone nova:Openstack116
```
Endpoint corresponding to ss1VirtIoTrunkPort1 is added to EPG (ss1nework1) and VLAN is provisioned.
EPG is updated:
- Name: 74cbf489-f3d9-41c7-bbb2-6cb7df33da6d
- Port: lag_1
Update EPG.
```
# openstack server create --flavor m1.large --image ubuntu --port $(neutron port-list | grep -w 'ss1VirtIoTrunkPort2' | awk '{print $2}') ss1VirtIoVM2 --availability-zone nova:Openstack117
```
Endpoint corresponding to ss1VirtIoTrunkPort2 is added to EPG(ss1nework2) and VLAN is provisioned.
EPG is updated:
- Name: 84cbf489-f3d9-41c7-bbb2-6cb7df33da6d
- Port: lag_1
Endpoint corresponding to ss1VirtIoSubport1 is added to EPG(ss1nework1) and VLAN is provisioned.

EPG is updated:
- Name: 74cbf489-f3d9-41c7-bbb2-6cb7df33da6d
- Port: lag_1
Extend ss1network1 to DC Edge.
```
# openstack port create ss2DcGwPort1 --device-owner network:dc_edge --host DCGW-1 --network ss1network1
```
Endpoint corresponding to host DCGW-1 is added to EPG (ss1network1) and VLAN is provisioned.
EPG is updated:
- Name: 74cbf489-f3d9-41c7-bbb2-6cb7df33da6d
- Port: lag_1, lag_4 (added)
Extend ss1network2 to DC Edge.
```
# openstack port create ss2DcGwPort1 --device-owner network:dc_edge --host DCGW-1 --network ss1network2
```
Endpoint corresponding to host DCGW-1 is added to EPG (ss1network2) and VLAN is provisioned.
EPG updated:
- Name: 84cbf489-f3d9-41c7-bbb2-6cb7df33da6d
- Port: lag_1, lag_4 (added)
