Campus Networking

Overview

For IT teams, the expectation continues: Do more with less. 


As campus networks become more business-critical, their complexity increases. They’re more difficult to operate as mobile, IoT, and cloud initiatives are added. Meanwhile, your network and security policies must scale automatically and consistently to accommodate new users and devices and keep productivity and efficiency high. 


At the intersection of these campus challenges is your opportunity to use artificial intelligence and machine learning to drive better user experiences and simplify network operations.

Juniper’s secure, AI-driven campus solution spans wired and wireless, from access to core and aggregation to the network edge.

A Campus fabric with EVPN-XLAN and Virtual Chassis. 

How Juniper Can Help

The AI DRIVEN Campus

The portfolio includes Juniper EX Series Switches and access points driven by the Mist AI engine and managed by the Mist Cloud. It’s API-driven and 100% programmable with open SDKs and ecosystems for seamless software upgrades and automation best practices.


  • See, automate, and protect your campus. Juniper Connected Security unifies all network elements into a threat-aware network and dynamically enforces security policies. SecIntel for EX Series Switches and access points provides security intelligence through detection and enforcement at every point of connection within a network, augmenting the defenses provided by traditional perimeter security technologies.

AI Driven Campus

The Collapsed Core Architecture

A collapsed core architecture takes the normal three-tier hierarchical network and collapses it into a two-tier network. In a two-tier network, the function of the switches in the core layer and distribution layer are “collapsed” into a combined core and distribution layer on a single switch. 


The example shows how to deploy a collapsed core architecture for a campus network.  The access point devices are connected to the access layer switches, which in turn are multihomed to the collapsed core switches. 


There are separate VLANs for employees, guests, and IoT devices. You can use use the EX4650 or the QFX5120 switch as the collapsed core switch. In this example, we use the EX4650 switch as the collapsed core switches and EX series switches as access switches.

In a campus environment, Juniper Access Points provide network access to end-user devices like access switches. With increased wireless performance and proliferation of mobile devices, wireless connectivity is becoming the primary mode of access on the campus network. Both real-time and bandwidth-demanding applications are running over wireless networks. However, the user expects the same level of network services (security, QoS, accessibility, and HA) as with a wired connection. Wireless access must be robust and reliable to deliver these demands.

The Juniper Networks Midsize 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 network. 

For the Midsize Campus Solution Reference Architecture using Mist Wired Assurance, the following modules are detailed:

 • Access • Aggregation • Edge

Midsize Branch Solution

Open Standards Design With AI

The midsize branch office solution from Juniper Networks offers a low-cost, low-maintenance, and secure solution using an SRX Series device to provide security, EX4300 family of switches to provide versatility, and Mist access points to provide a stellar wireless experience.


Enterprise networks respond to IT innovations and show their business agility by quickly adopting the software-defined WAN (SD-WAN) technology. 

The financial benefits of SD-WAN include automated provisioning to improve operational efficiency, lower WAN operational expenditures (OpEx), and lower capital expenditures (CapEx). 


You can use SD-WAN to optimize application experiences and network performance by prioritizing business-critical applications on the network links that guarantee Quality-of-service (QoS).

IP Clos Fabric Design For A Campus Network

An IP Clos fabric is also known as an "end-to-end" architecture because in this design EVPN-VXLAN functionality is extended to the access layer switches. IP Clos fabrics are optimal for large scale deployments and the support of IOT and device mobility.  


The use case shows how you can deploy a single campus fabric that uses EVPN in the control plane and VXLAN tunnels in the overlay network with Juniper Mist Access Points integration.

MACsec: Many federal government agencies mandate the use of MACsec encryption between access switches and various compute devices in the campus environment.

Compact and Fanless Access Devices: Advancements in integrated circuits now allow organizations to deploy silent, fanless switches throughout their campus environment.

Essential Campus Considerations

EVPN-VXLAN Campus Fabrics

Introduction

With an EVPN-VXLAN-based campus architecture, enterprises can easily add more core, distribution, and access layer devices to a growing business without having to redesign with a new set of devices to update the architecture.


Additionally, enterprises can deploy a common set of policies and services across campuses with support for Layer 2 and Layer 3 VPNs. By using a Layer 3 IP-based underlay with an EVPN-VXLAN overlay, campus network operators can deploy much larger networks than are otherwise available with traditional Layer 2 Ethernet-based architectures.

Juniper Network’s EVPN-VXLAN fabric is an efficient and scalable way to build and connect data center, public cloud, and campus networks. EVPN-VXLAN decouples the virtual topology from the physical topology to improve network flexibility and simplify management of the network. As a result, endpoints that require Layer 2 adjacency can be placed anywhere in the network and remain connected to the same logical Layer 2 network.


(Ethernet VPN) EVPN-(Virtual Extensible LAN) VXLAN provides large enterprises a common framework used to manage their campus and data center networks. An EVPN-VXLAN architecture supports efficient Layer 2/Layer 3 network connectivity with scale, simplicity, and agility, while also reducing OpEx.


The rapidly growing use of mobile devices (including the growing number of Internet of Things (IoT) devices), social media, and collaboration tools, adds an increasing number of endpoints to a network. To provide endpoint flexibility, EVPN-VXLAN decouples the underlay network (physical topology) from the overlay network (virtual topology). By using overlays, you gain the flexibility of providing Layer 2/Layer 3 connectivity between endpoints across campus and data centers, while maintaining a consistent underlay architecture.

In traditional Layer 2 networks, reachability information is distributed in the data plane through flooding. With EVPN-VXLAN networks, this activity moves to the control plane.

In traditional Layer 2 networks, reachability information is distributed in the data plane through flooding. With EVPN-VXLAN networks, this activity moves to the control plane.


EVPN is an extension to BGP that allows the network to carry endpoint reachability information such as Layer 2 MAC addresses and Layer 3 IP addresses. This control plane technology uses MP-BGP for MAC and IP address endpoint distribution, where MAC addresses are treated as routes. EVPN enables devices acting as VTEPs (see next section) to exchange reachability information with each other about their endpoints.


EVPN also provides multipath forwarding and redundancy through an all-active multihoming model. An endpoint or device can connect to two or more upstream devices and forward traffic using all the links. If a link or device fails, traffic continues to flow using the remaining active links.


Understanding VXLAN

What Is EVPN-VXLAN?

Understanding VXLAN

Because MAC learning is now handled in the control plane, EVPN can support different data plane encapsulation technologies between EVPN-VXLAN-enabled switches. With EVPN-VXLAN architectures, VXLAN provides the overlay data plane encapsulation.


Network overlays are created by encapsulating traffic and tunneling it over a physical network. T

Because MAC learning is now handled in the control plane, EVPN can support different data plane encapsulation technologies between EVPN-VXLAN-enabled switches. With EVPN-VXLAN architectures, VXLAN provides the overlay data plane encapsulation.


Network overlays are created by encapsulating traffic and tunneling it over a physical network. The VXLAN tunneling protocol encapsulates Layer 2 Ethernet frames in Layer 3 UDP packets, enabling Layer 2 virtual networks or subnets that can span the underlying physical Layer 3 network. The entity that performs VXLAN encapsulation and decapsulation is called a VXLAN tunnel endpoint (VTEP).


In a VXLAN overlay network, each Layer 2 subnet or segment is uniquely identified by a virtual network identifier (VNI). A VNI segments traffic the same way that a VLAN ID segments traffic - endpoints within the same virtual network can communicate directly with each other, while endpoints in different virtual networks require a device that supports inter-VNI (inter-VXLAN) routing.

Benefits of EVPN-VXLAN For Enterprises

Like many technologies, EVPN-VXLAN started out as a proprietary set of vendor-specific solutions and evolved into a standard to address several enterprise business challenges. Today, EVPN-VXLAN, a widely supported open standard, is evolving into the best way for enterprises to achieve multivendor network virtualization.


Deploying an EVPN-VXLAN framework provides the following benefits:


  • Programmable allowing you to easily automate
  • Open standards-based architecture ensures backwards and forwards interoperability
  • Integrated and efficient Layer 2/Layer 3 connectivity with control plane-based learning
  • Easy network scalability based on business needs
  • Network segmentation inside, and across multiple campuses and data centers allowing you to securely separate traffic
  • Minimized fault domain increases reliability of your network
  • MAC address mobility provides flexible yet simple deployment capabilities
