NextGen Port Extender Overview

Overview

The NextGen Port Extender (NGPE) is a solution for managing an aggregation network environment, in which a central aggregation device (AD) connects to multiple satellite devices (SD). The interfaces on each SD become extensions of the AD, allowing the AD to manage a large number of interfaces from a single device.

NGPE is the successor to Junos Fusion Provider Edge, and features key differences:

  • NGPE uses the same Junos OS on all participating devices. Junos Fusion requires Junos OS on the AD, and a separate satellite OS for SDs.

  • NGPE uses Ethernet VPN-Virtual Extensible Private LAN (EVPN-VXLAN) tunnels between the AD and SDs. Junos Fusion uses the IEEE 802.1BR standard.

We don't support NGPE and Junos Fusion configuration on the same devices since the two solutions aren't compatible.

Benefits

NGPE offers the following benefits:

  • Simplified Operations: The AD is the single management point for easier control.

  • Simplified Initial Configuration: NGPE utilizes Junos Node Unifier (JNU) and commit scripts to automate the initial setup. The user provides a few key parameters for JNU to configure the majority of the NGPE environment, including aggregate ethernet interfaces, underlay routing, and the EVPN-VXLAN overlay.

  • Cost Effective: NGPE supports low speed ports, which can reduce hardware costs and improve ROI. Low speed ports refers to 1G and 10G interfaces, compared to 100G interfaces.

  • Deployment Flexibility: Low speed connectivity options improve reachability to remote locations.

  • Satellte Provisioning: Easy onboarding of SDs with minimal touch provisioning.
