<ul>
<li>Uses Virtual Routing and Forwarding (VRF) to isolate network traffic</li>
<li>Creates Generic Routing Encapsulation (GRE) tunnels between transit gateway and on-premises routers</li>
<li>Implements separate Prod and NonProd routing domains across US East and EU West regions</li>
<li>Configures Direct Connect virtual interfaces and BGP sessions to exchange routes</li>
<li>Allows traffic segmentation between different network environments</li>
</ul>
<p>
The solution provides a method to extend AWS network segmentation to on-premises networks while maintaining isolation between production and non-production traffic across multiple locations.
