Easy Virtual Network (EVN)

Deliver traffic separation and path isolation capabilities on a shared network infrastructure with Easy Virtual Network (EVN). An IP-based network virtualization solution, EVN takes advantage of existing Virtual Routing and Forwarding (VRF)-Lite technology to simplify Layer 3 network virtualization, improve support for shared services, and enhance management and troubleshooting.

Easy Virtual Network (EVN) is an IP-based network virtualization solution that helps enable network administrators to provide traffic separation and path isolation on a shared network infrastructure.

EVN uses existing Virtual Route Forwarding (VRF)-Lite technology to:

• Simplify Layer 3 network virtualization.

• Improve shared services support.

• Enhance management, troubleshooting, and usability.

What Problems Does It Help Solve?

EVN reduces network virtualization configuration significantly across the entire network infrastructure with the Virtual Network Trunk. The traditional VRF-Lite solution requires creating one sub-interface per VRF on all switches and routers involved in the data path, creating a lot of burden in configuration management.
EVN removes the need for a per-VRF sub-interface by using the “vnet trunk” command. This helps reduce the amount of provisioning across the network infrastructure.

EVN enhances network virtualization troubleshooting by making VRF-Lite easier to deploy, operate, and scale. A routing context command mode allows network operators to perform troubleshooting issues that pertain specifically within a VRF without specifying the VRF name in every command.
