![600](_images/edge-deploy-workflow.png)
Creating the Edge Gateway ZTP ISO Image File
You must have port 443 open to the IP address of the Aviatrix Controller. For the required access for Edge Gateway deployment, refer to Aviatrix Edge Gateway Ports and Protocols. |
To create the Edge Gateway ISO image file, follow these steps.
-
Log in to Aviatrix Controller 6.8 or later.
-
Go to MULTI-CLOUD TRANSIT > Setup
-
In the Launch an Aviatrix Spoke Gateway page, enter the following values:
-
Cloud Type: Is always set to Aviatrix.
-
ZTP File Type: Select iso.
The ISO file is the equivalent of the Zero-Touch Provisioning (ZTP) token. ZTP allows network engineers to remotely deploy and provision network devices at remote locations. For KVM deployments, cloud-init is also supported.
The following cloud-init modules have been verified for Edge Gateway deployments: users, write_files, and chpasswd.
-
Gateway Name: Enter a name for the new Edge Gateway.
-
Site ID: Select an existing Site ID or create a new Site ID by entering a name (such as, edge-01) and click Add item.
For guidance on whether to select an existing Site ID or create a new one, see Edge Site ID Guidelines.
-
Management Connection Type: Select Static.
-
Management Connection Type: Select DHCP or Static, depending on your environment.
Steps (f-n) are applicable only for static IP configuration on the management interface. For IP and DNS settings, enter using the applicable format. For example, if the Edge Gateway’s WAN IP is 10.1.1.151, enter 10.1.1.151/24 or what your netmask is.
-
Management Interface IP/Mask: Enter the management interface IP/mask for the Edge VM.
-
Default Gateway IP: Enter the IP address of the Default Gateway for the Management Subnet.
-
Primary DNS Server: Enter the DNS server IP address.
-
Secondary DNS server: Enter the DNS server IP address, this field is optional.
-
WAN Interface IP/Mask: Enter the interface IP/mask for the Edge VM.
-
WAN Default Gateway: Enter the IP address of the Edge WAN interface.
-
Management Over Private Network: Check the box if the Edge management connection to the Aviatrix Controller is over a private network. Leave it unchecked if the connection is over the public internet.
-
Management Egress IP CIDR: Enter the IP address of the Edge VM visible to the Aviatrix Controller (IP address to be allowed in the Controller Security Group. This IP is optional and can be added later).
This field adds a security bypass filter rule for the incoming traffic on TCP/443 to your Controller.
-
LAN Interface IP/Mask: Enter the interface IP/mask for the Edge VM.
-
Active-Standby: Check the box for active-standby mode (see Active Standby Modes. Leave unchecked for Active-Active mode.
The Active-Active and Active-Standby modes are configured when you create the first Edge ZTP for a particular Site ID. If you need to change a configuration from Active-Active to Active-Standby, delete all the Edge Gateway for that Site ID and recreate the Edge Gateway with the new setting.
-
-
To create the ISO image file, click Create.
Aviatrix Controller prompts you to download the ISO file.
Controller downloads the ZTP .iso file to your Downloads folder.
-
Log in to your ESXi or KVM host and upload the .iso file to a datastore or storage device.
Controller displays a message that confirms when you have successfully downloaded the .iso file you created for the Edge gateway. The .iso file will expire 24 hours after you create it, so you must mount the .iso file to an Aviatrix Secure Edge VM to complete the Edge gateway registration within that timeframe, as you cannot download it again and will have to repeat the above steps.
