Overview: Midsize Enterprise Campus Solution



Campus networks are constantly evolving and growing at a rapid rate. No longer merely comprised of homogenous desktops and printers, a campus now includes an array of IP devices: phones, wireless access points, tablets, and more. Enterprise knowledge workers can work anywhere, as their access permits. Providing a consistent experience, regardless of how or where the user connects, can increase the overall productivity of an enterprise. Enterprises must build a network that can provide flexibility while protecting critical data from unauthorized access.

About Juniper Networks Validated Solutions

Juniper Networks validated solutions are complete domain architectures that are expert designed, lab tested, and documented to provide guidance in the deployment of complex solutions. Juniper Networks solution validation labs put all solutions through extensive testing using both simulation and live network elements to ensure comprehensive validation of all published solutions. Customer use cases, common domain examples, and field experience are combined to generate prescriptive configurations and architectures to guide customer and partner implementations of Juniper solutions. This approach enables partners and customers to reduce the time needed to certify and verify new designs by providing tested, prescriptive configurations to use as a baseline.

The Juniper Networks Midsize Enterprise Campus solution addresses the end-to-end validated architecture required to deliver a design and implementation strategy for today’s campus environments, built upon a reliable and secure Juniper foundation. Validation comes through testing that encompasses not only the basic connectivity required to provide service for the campus, but also test the scale and policy on the entire design, resulting in an architecture that the customers can trust.


The Juniper Networks Midsize Enterprise Campus solution is designed to meet the needs of an increasingly complex network while providing a key enabler for productivity. This reference architecture document serves as a high-level overview and includes the challenges, design considerations, and recommendations for midsize enterprise campus design. More in-depth technical details can be found in the Juniper Networks EVPN-VXLAN Campus Architectures.


The Juniper Networks Midsize Enterprise Campus solution is built upon a standard solution architectural approach. The baseline architecture is based on a series of building blocks, built by Juniper Networks, that are meant to address the entire enterprise network. Other solution reference architectures include the Juniper Networks Enterprise WAN Solution Architecture and the Juniper Networks Metafabric Solution Architecture.

For the Midsize Enterprise Solution Reference Architecture, the following modules are detailed:

  • Access

  • Aggregation

  • Core

  • Edge

Each of the modules take into consideration the following elements and design requirements:

  • Policy orchestration

  • Network management

  • Security

  • Quality of service (QoS)

  • High availability (HA) and resiliency

Figure 1 illustrates the solution modules and the design considerations described in this reference architecture.
