Building Highly Resilient Networks in Network Edge - Part 4 - Virtual Connections

This is the fourth and final part of a series of posts highlighting the best practices for customers who require highly resilient networks in Network Edge. This entry highlights how to build resilient Fabric Virtual Connections.

• Virtual connections allow NE devices to connect to CSPs, NSPs and ISPs as well as co-location​
• The same logic still applies: the NE device plane determines which Fabric switch is used​
• The VC connection workflow is very similar to the EVP-LAN workflow with some differences​
• Customers that require VC link resiliency should create two or more VCs to their NE devices with each connection traversing the Primary and Secondary fabric switch​
• Some CSPs like Azure require resiliency but most do not​
• The Fabric portal allows connections to be created as redundant or single-legged​
• The workflow is highlighted in the next few slides for both Redundant and Clustered devices
