# Support for IPv6 on Aviatrix Gateways

> Enable IPv6 support on Aviatrix CoPilot and configure IPv6 on Transit and Spoke Gateways.

This section describes the where the IPv6 support is enabled on Aviatrix
Gateways for each Controller release.

## Support for IPv6 on the Aviatrix Controller

To enable IPv6 support **on the Aviatrix Controller**, in CoPilot go to
**Settings** > **Configuration** > **General** and turn on the **Support for
IPv6** toggle.

When IPv6 support is enabled on the Controller, CoPilot displays IPv6-related
fields in the following areas:

**Controller version 9.0** The Controller supports the following IPv6-related
features on top of the features from Controller version 8.2:

* Global IPv6 route summarization
* Government cloud (AWS GovCloud and Azure Government) support
* Equinix Edge integration
* Unique Local Address (ULA) support
* Bidirectional Forwarding Detection (BFD) for IPv6 BGP
* BGP over LAN for Azure
* BGP over GRE
* Fortinet and Checkpoint Firenet support
* IKEv2 enforcement for IPv6 BGPoIPSec
* Enhanced IPv6 diagnostic tools

**Controller version 8.2**

* Creation pages of the VPC/VNets (AWS and Azure)

* Creation and edit pages of the Transit and Spoke gateways of AWS and Azure

* Gateway details pages

* Creation pages of AEP and Equinix Spoke gateways (on LAN interfaces section)

* Network Segmentation pages (Transit-Spoke peering)

* External connection to External Device pages

  * BGP over IPSec

## Support for IPv6 on Aviatrix Gateways

Aviatrix gateways support IPv6 addressing and routing. When you enable IPv6
support on a gateway, the Aviatrix Controller automatically creates an IPv6 CIDR
block for the gateway based on the allocation of the cloud provider.

  Enable **Support for IPv6** on the Aviatrix Controller from **Settings** > **Configuration** > **General** in CoPilot to see IPv6-related options.
  On Controller version 8.2 and later, IPv6 on Gateways applies to AWS and Azure. On Controller version 9.0 and later, IPv6 also applies to GCP Transit and Spoke Gateways and expanded Site-to-Cloud, Edge, government cloud, and FireNet scenarios described in the <a href={"/docs/enterprise/" + "10.1" + "/concepts-architectures/components/connectivity/ipv6-overview"}>IPv6 Overview</a>.
