# Networking

![university_Network.drawio.png](university_Network.drawio.png)

## Openstack control networks

- These networks reside on the primary 1G ethernet adapter.
- The IPMI network is usually only used by the undercloud, however to facilitate IPMI fencing for Instance-HA the Openstack controller nodes will have a logical interface

| Network | VLAN | IP Range |     |
| --- | --- | --- | --- |
| ControlPlane | 1 Native | 10.122.0.0/24 |     |
| IPMI | 2   | 10.122.1.0/24 |     |

## Openstack service networks

- The logical networks reside upon an OVS bridge across an LACP bond on the 2x Mellanox 25G ethernet adapters in each node.
- The 2x Mellanox 25G ethernet adapters are cabled to 100G switch1 and 100G switch2 respectively, the switch handles the LACP bond as one logical entity across switches with a CLAG.

| Network | VLAN | IP Range |     |
| --- | --- | --- | --- |
| Storage Mgmt | 14  | 10.122.12.0/24 |     |
| Storage | 13  | 10.122.10.0/24 |     |
| InternalApi | 12  | 10.122.6.0/24 |     |
| Tenant | 11  | 10.122.8.0/24 |     |
| External | 1214 | 10.121.4.0/24 Gateway 10.121.4.1 |     |

## Ceph service networks

Use Openstack "Storage Mgmt" for the Ceph public network.

| Network | VLAN | IP Range |     |
| --- | --- | --- | --- |
| Cluster Network | 15  | 10.122.14.0/24 |     |
| Public Network (Openstack Storage) | 13  | 10.122.10.0/24 |     |
| Management (Openstack Storage Mgmt) | 14  | 10.122.12.0/24 |     |
