## Extend Aviatrix to Edge Locations
This diagram illustrates Aviatrix Edge Gateways deployed at multiple edge
locations.
## Aviatrix Edge Spoke Gateway for On-Premises
### Cloud Orchestration and Simplified Onboarding
Ease of onboarding
* Instantly onboard HW orchestrated via Cloud
* Manage and operate the Edge HW and network software via cloud
* No IT expertise required to connect and deploy the Edge HW
Drive better cost & FTE efficiencies
* Simplified deployment with automation
* Deploy Edge network software to multiple devices at scale via Cloud
* Single automation stack across cloud and on-prem
* Faster deployment and onboarding of connectivity from on-prem to cloud and
on-prem to multi-cloud
### Increased Performance, Reduced Operational Overhead, and Bottlenecks Removed
* IPSec Encrypted line rate throughput from cloud to on-prem via public or
private connectivity
* Repeatable architecture
* Same overlay from Cloud to Edge
* Consistent security protocols
* Config driven via cloud and consistent secure IPSec state across Edge
* E2E visibility – Within Cloud and Cloud to Edge
## Multiple Edge Spoke Gateways for Multiple Edge Sites
This use case illustrates Edge Gateways with BGP connection to a VIP. The Edge
Gateways can be set up at multiple edge sites as shown in the diagram with Site
A and Site B.
## Multiple Edge Spoke Gateways for Single Edge Site
This use case illustrates multiple Edge Gateways on the same edge site for
horizontal scaling or multiple Active-Active connections from cloud to edge.
## Edge Spoke Gateway Connectivity to Different LAN Routers (Multiple Sites)
This use case illustrates Edge Gateways on different edge sites with active and
standby peering connections to different LAN routers.
## Edge Spoke Gateway Connectivity to Different LAN Routers (Single Site)
This use case illustrates multiple Edge Gateways on the same edge site with
peering connections to different LAN routers.
Only Active-Active high availability mode is supported with more than two Edge
Gateways on the same site.
## Edge Spoke Gateway to AWS TGW Domain with FireNet Enabled
When FireNet inspection is enabled for an AWS TGW domain, the Aviatrix Edge
domain cannot be associated to that domain. Because of a limitation that is
attributed to how AWS configures its TGW domains, the on-premises routes from
the Edge domain are not installed in the Spoke TGW route table via the Aviatrix
Transit Gateway.
To overcome the AWS TGW domain limitation, create another pair of Edge Gateways
and associate the gateways to the Transit Gateways with the associated TGWs
without segmentation on Edge.
