Overview of the Enterprise Routing and Switching, Professional (JNCIP-ENT) Certification

The Enterprise Routing and Switching (JNCIP-ENT) certification is positioned at the professional level of Juniper’s Enterprise track. It is designed for experienced networking professionals who work extensively with Juniper Networks enterprise routing and switching platforms and possess strong understanding of the Junos operating system.

This certification validates advanced knowledge and real-world skills in routing technologies, switching, troubleshooting, and platform configuration. Passing the JN0-650 exam demonstrates your capability to architect, deploy, and manage enterprise-scale networks using Juniper solutions.

Enterprise Routing and Switching Certification Path

The Enterprise Routing and Switching track consists of four progressive certifications:

● JNCIA-Junos (JN0-105) – Associate-level foundation in Junos basics.

● JNCIS-ENT (JN0-351) – Specialist-level certification covering intermediate enterprise routing and switching skills.

● JNCIP-ENT (JN0-650) – Professional-level certification focusing on advanced routing, switching, and troubleshooting.

● JNCIE-ENT – Expert-level hands-on lab exam validating real-world engineering ability.

To attempt the JN0-650, you must first earn the JNCIS-ENT certification.

Exam Information for JN0-650 (JNCIP-ENT)

The exam is designed to test deep technical understanding and the ability to apply concepts in real-world network environments.

Detailed Breakdown of the JN0-650 JNCIP-ENT Exam Objectives

Below is a clear breakdown of what the exam covers. Each section includes both conceptual understanding and configuration/troubleshooting capabilities.

1. Interior Gateway Protocols (IGPs)

You must understand the concepts and operation of IGPs such as OSPF and IS-IS.

Topics include:

● Routing concepts and packet flow

● Adjacency formation

● LSA/LSP propagation

● Route selection behavior

You may need to identify or fix IGP-related misconfigurations based on given scenarios.

2. Border Gateway Protocol (BGP)

This section validates your advanced knowledge of inter-domain routing:

● BGP attributes and route advertisement

● iBGP vs eBGP operations

● Route selection rules

● Policy configuration (import/export)

You must be able to configure, monitor, and troubleshoot BGP in practical Junos environments.

3. IP Multicast

You will be tested on:

● Multicast addressing and forwarding

● PIM concepts (Dense Mode, Sparse Mode, SSM)

● RPF checks

● Rendezvous Point operation

Scenarios may involve correcting multicast group delivery problems or verifying proper configuration.

4. Ethernet Switching and Spanning Tree

Advanced switching features include:

● VLANs, Q-in-Q, and Layer 2 forwarding

● Storm control and loop prevention

● LAG and LACP behavior

Spanning Tree coverage includes:

● MSTP (Multiple Spanning Tree Protocol)

● VSTP (VLAN Spanning Tree Protocol)

Expect tasks involving detecting switching loops, verifying STP topology, or resolving VLAN-related issues.

5. Layer 2 Authentication and Access Control

You must understand and configure:

● 802.1X port-based authentication

● MAC RADIUS

● Captive portal workflows

● Dynamic VLAN assignment

Troubleshooting scenarios may involve failed authentication attempts or incorrect access-control behavior.

6. IP Telephony Features

Important telephony-related concepts include:

● LLDP-MED

● Voice VLANs

● QoS for voice traffic

You will need to interpret telephony configurations and resolve common issues in converged networks.

7. Class of Service (CoS)

CoS knowledge includes:

● Traffic classification

● Queuing mechanisms

● Scheduling and shaping

● Rewrite and forwarding behaviors

Expect items testing your ability to apply CoS correctly in Layer 2 and Layer 3 environments.

8. Ethernet VPN (EVPN)

EVPN is one of the most advanced topics in the exam:

● EVPN control plane operation

● VXLAN encapsulation

● MAC learning and advertisement

● Multi-homing and DF election

You should be comfortable configuring, verifying, and troubleshooting EVPN deployments.

Best Study Tips to Pass the JNCIP-ENT JN0-650 Exam

Passing the JNCIP-ENT exam requires a strategic approach that combines practical experience, structured study, and the right resources. Here are proven tips to help you succeed:

1. Build Hands-On Experience with Junos OS

Lab practice is essential. Use vMX, vSRX, or Juniper’s Open Learning labs to simulate real configurations for OSPF, BGP, EVPN, CoS, and multicast. The more you configure, break, and fix, the more confident you become.

2. Study the Official Juniper Documentation

Juniper’s TechLibrary is one of the richest documentation centers in the networking industry. Focus on protocol behavior, operational commands, and troubleshooting guidelines.

3. Master the Exam Objectives Section by Section

Break down your study sessions by domain. For each domain, ensure you can be familiar with all the exam objectives to prepare for your exam thoroughly.

4. Use Passcert’s Latest JN0-650 Dumps for Realistic Practice

Passcert’s updated dumps provide real-world question formats that mirror the exam style. Practicing these questions helps reinforce your understanding and reduces test-day uncertainty.

5. Take Practice Tests Under Timed Conditions

Simulate the 90-minute exam window and challenge yourself to complete 65 questions. This strengthens time management and improves accuracy.
