Segmenting Layer 3 Networks with VRFs

I am creating a multi-part series that focuses on Layer 3 network segmentation. This post serves as a landing point and aggregation place for these topics. As the series is built out, the individual links will be available below.

Articles in this Series

The basic topology is shown below. Each article will consist of the configuration information and relevant validation. This should serve as a very good starting point for anyone struggling with building out a common network with strict security zones requiring areas of isolation.
