Dear friend in this tutorial we will see routing configuration in different subnets in openstack. We will also see how to update Image in openstack, how to create Network, how to create a flavour and how to create a router for network routing in OpenStack.
We follow these steps to perform network routing configuration in different subnets in openstack.
- Qcow2 image upload in openstack.
- Flavor creation in openstack.
- OVS Network creation in openstack.
- Network subnet creation in openstack.
- SRIOV Network and port creation in openstack
- Instance launch in openstack
- Router creation for network routing configuration in openstack.
- check network routing between two different subnet.
So lets start step by steps configuration and see Network routing between to two different subnet in openstack.
Qcow2 image upload in openstack.
In this section we will see how to upload image in qcow2 format in openstack library. We can use glance image-create command to upload image in openstack. Like below:-
[stack@undercloud (overcloudrc) ~]$ glance image-create --name Rhel7Genereic --file "/home/stack/redhat-7.4-ATP-V6.qcow2" --disk-format qcow2 --container-format bare --visibility "private"

We can list down created image with below commands.

Flavor creation in openstack.
Now we will see how to create flavor in openstack. In the flavor we have to define Number of CPU, Memory size and Hard Disk size for our instance.
[stack@undercloud (overcloudrc) ~]$ nova flavor-create SMALL_1 auto 4096 0 4 +--------------------------------------+---------+-----------+------+-----------+------+-------+-------------+-----------+-------------+ | ID | Name | Memory_MB | Disk | Ephemeral | Swap | VCPUs | RXTX_Factor | Is_Public | Description | +--------------------------------------+---------+-----------+------+-----------+------+-------+-------------+-----------+-------------+ | bec4a148-1b03-47e1-a793-96a905c22ec4 | SMALL_1 | 4096 | 0 | 0 | | 4 | 1.0 | True | - | +--------------------------------------+---------+-----------+------+-----------+------+-------+-------------+-----------+-------------+ [stack@undercloud (overcloudrc) ~]$

OVS Network creation in openstack.
Now I am going to create OVS network with VLAN 10 and network is 10.10.10.0/24 and physnet is 0 where OVS network is mapped.

Openstack network list command can be use to display created network. Like below:-

Network subnet creation in openstack.
After network creation we can create subnet for that network. like below:-
[stack@undercloud (overcloudrc) ~]$ neutron subnet-create Net-10 10.10.10.0/24 --name Subnet-Net-10 --enable-dhcp --gateway 10.10.10.1 --allocation-pool start=10.10.10.10,end=10.10.10.100

Now you can see in above screen shot we have successfully launched both instances.
Router creation for network routing in openstack.
Now we can create Openstack Virtual router for routing between two different subnet. Like below:-
[stack@undercloud (overcloudrc) ~]$ neutron router-create router neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead. Created a new router: +-------------------------+--------------------------------------+ | Field | Value | +-------------------------+--------------------------------------+ | admin_state_up | True | | availability_zone_hints | | | availability_zones | | | created_at | 2019-08-31T12:41:38Z | | description | | | external_gateway_info | | | flavor_id | | | ha | True | | id | 8cee8581-afc5-43ff-953c-add3fd1f1db6 | | name | router | | project_id | 4e076fffb06d42f09c5994a0fd781cfd | | revision_number | 1 | | routes | | | status | ACTIVE | | tags | | | tenant_id | 4e076fffb06d42f09c5994a0fd781cfd | | updated_at | 2019-08-31T12:41:38Z | +-------------------------+--------------------------------------+ [stack@undercloud (overcloudrc) ~]$
After router creation, we need to be add our both network subnet in router to access both network from both side. Like below:-
[stack@undercloud (overcloudrc) ~]$ neutron router-interface-add 8cee8581-afc5-43ff-953c-add3fd1f1db6 SRIOV-Net-Subnet neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead. Added interface edc78a21-c53a-420c-a846-aa2f2dce8ab8 to router 8cee8581-afc5-43ff-953c-add3fd1f1db6. [stack@undercloud (overcloudrc) ~]$ neutron router-interface-add 8cee8581-afc5-43ff-953c-add3fd1f1db6 Subnet-Net-10 neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead. Added interface 0aaaa722-22fc-47f0-adfe-d28671c80d7c to router 8cee8581-afc5-43ff-953c-add3fd1f1db6. [stack@undercloud (overcloudrc) ~]$
We have successfully added subnet in router. After that we can go to Dashboard and check our network routing is working or not?
Make sure your security profile is updated and ICMP should be allow from all networks then we can see our OVS networ VM will be accessible from SRIOV network.
You can see in above screen shot we are able to access OVS network from SRIOV network.
That’s all, We have successfully configured network routing between two different subnets in openstack.
No its created by me.
