Juniper JNCIP-SP (JN0-664) is a professional-grade core certification that focuses on practical applications of key technologies such as advanced routing and MPLS VPN.

1. Introduction to the Juniper JNCIP-SP certification

Juniper JNCIP-SP (JN0-664) is a professional level core certification in the Juniper Networks certification system, officially known as "Juniper Networks Certified Internet Professional - Service Provider Routing and Switching." It focuses on verifying practitioners' practical abilities in designing, deploying, optimizing, and troubleshooting advanced routing and switching technologies in complex network environments of service providers.

Juniper JNCIP-SP is a key advanced link in Juniper's service provider certification system. It is the core technical certificate for transitioning from "intermediate network engineer" to "service provider network expert", and also the "technical backbone certification" in the service provider network field.

The service provider network needs to meet the core requirements of "high bandwidth, high reliability, high availability, and multi service carrying," involving complex scenarios such as large-scale routing scheduling, MPLS VPN service delivery, traffic engineering, and cross domain interconnection.

The core of JNCIP-SP certification is to cultivate "Service Provider Network Practical Senior Engineers" who are not simply technical theorists, but are capable of independently addressing the core challenges of service provider networks, ensuring the stable operation of backbone networks and efficient delivery of multiple services.

When deploying cross regional MPLS VPN services for telecom operators, JNCIP-SP certificate holders will design a layered BGP routing architecture to solve the problem of large-scale routing convergence; Optimize backbone network bandwidth allocation through RSVP-TE traffic engineering to ensure low latency for critical services such as voice and video; Deploy the BFD+FRR fast rerouting mechanism to achieve millisecond level switching in case of failure and improve network availability.

2. The Competitive Edge of Juniper JNCIP-SP Certification 

JNCIP-SP is a globally recognized professional level certification in the field of service provider networks, with high recognition among ISPs and Juniper partners. When recruiting senior network engineers and dedicated line technical leaders, they are often listed as "essential requirements" and are the core distinguishing factor between intermediate and advanced service provider network talents.

JNCIP-SP certification focuses on the core challenges of service provider networks. After passing, it can prove the ability to independently solve complex network problems, directly lead operator level network projects, become the technical backbone of the team, and have significant competitive advantages in project bidding.

Holders of JNCIP-SP certification can join Juniper's global service provider technology community to obtain official exclusive backbone network solution documents, advanced technical support, and preview of new version features; prioritize participation in Juniper Global Technology Summit and specialized training for service providers, connect with top experts and benchmark project resources in the industry, and lay the foundation for advanced expert level certification.

3. Core Components of the Juniper JNCIP-SP (JN0-664) Certification

For senior network engineers who are committed to becoming operator level network experts and wish to master the core technology of service provider networks, Juniper Service Provider Advanced Technology Certification is a highly valuable professional qualification.

JN0-664 certification focuses deeply on key technologies such as advanced routing, MPLS and VPN architecture, and service quality assurance in the operator network environment, aiming to comprehensively verify your advanced technical capabilities in designing, deploying, and operating large-scale service provider networks.

As the core of authentication, advanced routing protocols require proficiency in large-scale deployment solutions such as BGP route reflectors and alliances, mastery of special area design and optimization techniques for OSPF/IS-IS, and proficiency in using Junos policy framework to achieve refined routing control and filtering.

MPLS and VPN technology are the cornerstone of service provider networks. You will delve into the principles of MPLS label forwarding and LDP protocol, master the deployment of mainstream VPN services and understand the application of cutting-edge technologies such as EVPN and MPLS traffic engineering.

The service provider exchange technology module focuses on carrier level layer 2 networks. You need to master the implementation of QinQ dual layer labeling technology and be able to deploy multi chassis link aggregation and ring network protection mechanisms to build a highly reliable carrier level switching network.

Service quality and traffic management require you to learn how to design a complete QoS architecture based on the DiffServ model, including traffic classification, labeling, supervision, and shaping. By configuring advanced queue scheduling and congestion avoidance mechanisms, you can provide differentiated service quality assurance for different levels of business.

Network high availability and resilience require you to master key technologies to improve network reliability, including configuring BFD millisecond level fault detection, Graceful Restart and other high availability features of routing protocols, as well as deploying protection mechanisms such as MPLS fast rerouting.

Finally, you need to have the ability to operate large-scale carrier networks, be able to use Junos advanced diagnostic commands to monitor network status, and systematically troubleshoot complex faults.

4. What are the requirements to be a Juniper JNCIP-SP?

(1) Qualification prerequisites:

Before obtaining JN0-664 certification, you need to first pass JNCIS-SP (JN0-363) certification and possess basic network technology and Junos operation experience as a service provider.

We recommend that you have 3-5 years of practical experience in service provider networks or large enterprise wide area networks, and be familiar with backbone and dedicated network architectures; gain a deep understanding of TCP/IP protocol, core routing and switching technologies, and master the advanced configuration logic of Junos operating system. 

(2) Training and examinations:

JN0-664 has a total of approximately 65 questions, including multiple-choice questions, situational analysis questions, and advanced configuration simulation questions. The exam lasts for 120 minutes. Full score of 1000 points, reaching 700 points or above to pass.

The exam fee is approximately $400 (with slight differences in tax fees in different regions). 

(3) Qualification maintenance:

The JN0-664 certificate is valid for 3 years, and you need to pass Juniper's higher-level certification or retake the JN0-664 exam within the validity period to renew the certificate's validity.
