Juniper EX9251 switches are based on Juniper One custom silicon, an ASIC designed by Juniper that provides a programmable Packet Forwarding Engine (PFE) and natively supports networking protocols such as virtualization using MPLS over IP and overlay network protocols. ASIC micro code changes, delivered through updates to Juniper Networks Junos operating system, protect investments by allowing existing hardware to support new or future networking protocols. As a key component of Juniper’s Cloud-Enabled Enterprise architecture, EX9250 switches provide a simple, open, and smart approach to building enterprise networks. The EX9250 switches support Junos Fusion Enterprise technology, which enables a large number of devices deployed throughout a building to be managed as a single logical device. Juniper EX9251 switches also support Data Center Interconnect (DCI), critical to workload mobility and application availability, by delivering leading technologies such as MPLS, virtual private LAN service (VPLS), and EVPN. Juniper EX9251 switches offer Evolved Enterprise Core capabilities that allow the creation of larger networks supporting both Layer 2 and Layer 3 application traffic. An Evolved Enterprise Core is enabled by combining technologies such as EVPN and VXLAN. EVPN uses control plane-based learning to ensure efficient network utilization and natively supports active/active multihoming. VXLAN overlay with EVPN allows L2 connectivity across the network while providing active/active redundancy, aliasing, and mass media access control (MAC) withdrawal. In an Evolved Enterprise Core, the provider edge (PE) switch/router can, in most cases, also use a VXLAN L3 gateway and route between VXLAN segments when required. Since the core is a standard IP network, EVPN/VXLAN allows the creation of an evolved core without having to replace the rest of the core infrastructure. Enabling an evolved core with EVPN provides flexibility by integrating with Junos Fusion and other technologies in the distribution/access layer, paving the way for a broader EVPN deployment over time. Juniper EX9251 line of switches is designed with simplicity in mind to enable the Self-Driving Network, with the goal of detecting and correcting network faults and anomalies before services or customer experiences can be impacted. The following capabilities, integrated into the EX9250 switches, make this possible.
