Introduction
Within this 3 part series on how to build a virtual Nuage SDN lab, we previously looked at the topology, the OpenStack installation and VSD deployment.
Next, we will now look at the steps involved in installing the VSC (Virtualized Services Controller).
Once installed our controller will talk XMPP to the management plane (VSD). Once the VRS's are installed (Part 3) the controller will talk to each virtual switch (VRS) via OpenFlow.
Figure 1 - Nuage VCS Overview
Overview
Let's look at an overview of the steps.
- Deploy VMware OVF.
- Configure VSC settings.
- Verify Connectivity.
Note: Attempts to run the VSC VM on top of a VM (i.e nested) failed. It crashed and hung at the point of trying to load the kernel. As a result, I decided to just deploy the OVF.
Deploy OVF
First, deploy your VSC OVF from within your vCenter. Like so,
Figure 2 - VSC deployment via OVF
You will be asked a number of inputs around the configuration. Complete as per the below:
| AS | None |
| BGP Group | Internal |
| BGP Peer 1 | None |
| BGP Peer 2 | None |
| DHCP | False |
| DNS Server 1 | 172.29.236.139 |
| DNS Server 2 | 8.8.8.8 |
| DNS Server 3 | 4.2.2.2 |
| DNS search domain | lab.local |
| Datapath IP | None |
| Management IP | 172.29.236.186/24 |
| SNTP | None |
| Static Routes | 0.0.0.0/1 next-hop 172.29.236.1
128.0.0.0/1 next-hop 172.29.236.1 |
| System IP | 172.29.236.186 |
| VSC name | vsc01 |
| XMPP Server | vsc01:[email protected] |
Configure VSC
Next, log into the VSC via SSH with the credentials of admin/admin.
The VSC configuration consists of:
- BOF (Boot Options File) - Contains the parameters in order to boot the device, i.e image, config location etc.
- Main Configuration - Contains all of the main configuration, such as BGP config, LAG settings etc.
Based on this perform a show bof and confirm you have the below:
A:vsc01>config>router# show bof

Next run an admin display-config and confirm the below is configured.

Verify VSD Connectivity
Finally, we verify connectivity to the VSD via the following command. Like so,
