Figure 4: Campus fabrics showing Virtual Chassis and EVPN-VXLAN-based architectures

All three topologies are standards-based and interoperable with

third-party vendors.

The EX4100 switches can be deployed in campus and branch

access layer networks in the EVPN-VXLAN architectures shown in

Figure 4.

Managing AI-Driven Campus Fabric with the Juniper Mist Cloud

Juniper Mist Wired Assurance brings cloud management and Mist

AI to the campus fabric. It sets a new standard that moves away

from traditional network management towards AI-driven

operations, while delivering better experiences to connected

devices. Juniper Mist Cloud streamlines deployment and

management of campus fabric architectures by allowing:

• Automated deployment and zero-touch deployment (ZTD)

• Anomaly detection

• Root cause analysis

Chassis-Class Availability

The EX4100 switches deliver high availability through redundant

power supplies and fans, graceful Routing Engine switchover

(GRES), and nonstop bridging and routing when deployed in a

Virtual Chassis configuration.

In a Virtual Chassis configuration, each EX4100 switch is capable of

functioning as a Routing Engine (RE). When two or more EX4100

switches are interconnected, a single control plane is shared among

all Virtual Chassis member switches. Junos OS automatically

initiates an election process to assign a primary (active) and backup

(hot-standby) RE. An integrated L2 and L3 GRES feature maintains

uninterrupted access to applications, services, and IP

communications in the unlikely event of a primary RE failure.
