Public VCF as-a-Service - Declaring the public IP gateway in VCD

View as Markdown

Declare the gateway of your public IP block on your VCD Virtual Datacenter to use public IPs on your VMs

Objective

When you order a new Public VCF as-a-Service organization, a vRack and a block of public IP addresses are delivered. To assign those public IPs to workloads, you must declare the block’s gateway inside the target VCD Virtual Datacenter.

This guide shows how to retrieve the correct gateway and add it to your VDC.

Requirements

OVHcloud Control Panel Access

  • Direct link:
  • Navigation path: Hosted Private Cloud > Public VCF as-a-Service > Select your VCF service

Instructions

  1. Select your organization.

    Open organization

  2. Open the Virtual Datacenters tab and select the VDC where you want to use the public IPs.

    Select VDC and check vRack

In General information, verify that the vRack shown is the one linked to your public IP block.

Select VDC and check vRack

  1. Select the vRack tab.

    Select the vRack tab

Locate the vRack segment named vRack segment - VLAN0 or vRack segment - PUBLIC.

Click the three dot menu â‹® and Add a subnet.

Add a subnet on the vRack segment

  1. In the modal, enter the gateway in CIDR form for your public IP block, then confirm. The gateway is the last usable host of the block.

    Example: for 203.0.113.0/29, the last usable host is 203.0.113.6 so enter 203.0.113.6/29. You can use any standard IP calculator to verify.

    Enter gateway CIDR

  2. Wait a few seconds and refresh the page. The subnet gateway should now appear on the segment.

Use the gateway when creating workloads

  • When creating a vApp or VM in VCD, pick the corresponding Organization VDC network and choose a Direct network type to see the available public gateways.
Select Direct network type and gateway
Info

Known limitation:

In the current VCF version, the Gateway CIDR field may display the first gateway declared on your VLAN0 segment, even if you selected another one. This is a visual only issue and does not affect IP assignment. Use any address from the selected public block on your VM, consistent with the gateway you chose in Organization VDC network connection.
