More enterprises are deploying SDS, but they sometimes run into problems related to support and scalability.
For those following the VRF Series, we currently have a topology built that consists of a segmented Layer 3 first hop network and remotely networked by carrying the isolation from the BrWan router to Main. This article covers, shared services, the next step in our journey to understanding VRFs for Segmented Layer 3 Networks.
The configuration focus is solely on the router Main. The shared services VRF that will be created could serve as a place to connect something that all other VRFs must have access to. Organizations should evaluate their requirements closely before deploying this configuration.
An organization that requires stateful inspection between two areas may choose to connect two or more VRFs together using an L4 or Next Generation Firewall (we will cover this in Article 5). The security ramification of having a shared services VRF, as described in this article, is that devices connected in this area could be used as a proxy into other areas. Therefore, careful planning and proper device level security is important prior to deploying this type of architecture.
The technologies covered here include:

As many of you know, I was born in Turkey. And unfortunately, the educational system of that country is very weak. And guess what: If you can’t afford to go to private school in Turkey, you may not be able to learn English in the government school. However, if you are a very diligent student, […]
