Adding a New Tier-1 Gateway in NSX – Articles

OVHcloud provides you with NSX with two gateways, a north-south gateway (ovh-T0-gw) and an east-west gateway (ovh-T1-gw). You can create additional east-west gateways.

Learn how to add an east-west (Tier-1 Gateway) gateway to your NSX configuration.

Requirements

Being an administrative contact of your Hosted Private Cloud infrastructure to receive login credentials.
A user account with access to the OVHcloud Control Panel.
Having NSX deployed.

NOTE: Through your NSX interface, you can create north-south gateways. We strongly advise you not to do it because some options are not available and you will not be able to make such a gateway work correctly.

For more information on NSX at OVHcloud, please refer to our Getting Started with NSX guide.

Instructions

We will add a new east-west gateway (Tier-1-Gateways) and link it to the north-south gateway provided by OVHcloud (ovh-T0-gw).

Next, we will create a segment and attach a virtual machine to it.

Creation of the new east-west gateway

In the NSX interface, go to the Networking tab.

Click on Tier-1 Gateway on the left.
Then click on ADD TIER-1 GATEWAY.

Enter the name of your new gateway as new-T1-gw below Name and fill in these parameters:

Linked Tier-0-Gateway : Your north-south gateway ovh-T0-gw.
Edge Cluster : Your edgeXXX-X.
Fail Over : Non Preemptive.
Edge Pool Allocation Size : Routing.

Then click the Arrow to the left of Route Advertisement.

Select the button to the right of All Connected Segment & Service Ports if you want to connect outside this gateway, then click SAVE.

Click NO.

Your new gateway is displayed and we can see it connected to your north-south gateway (ovh-T0-gw).

Click Network Topology in the vertical menu bar to the left to view your network topology and to display your new new-T1-gw gateway connected to ovh-T0-gw.
