What Is JNCIP-SP Certification?

What the Credential Actually Is

JNCIP-SP stands for Juniper Networks Certified Professional, Service Provider Routing and Switching. It is a professional-level certification from Juniper Networks, whose current certification pages carry HPE Juniper Networking branding. It is aimed at networking professionals who already have advanced knowledge of Junos OS routing and switching and who work with, or want to work with, service provider networks.

If you have seen the acronym used elsewhere, set that aside. This article concerns only the Juniper credential. For shorter definitions of the name, see What Does JNCIP-SP Stand For? and JNCIP-SP Meaning.

The credential is earned by passing one written exam, JN0-664, which is built on Junos OS 22.3. The issuer's overview does not publish a separately dated blueprint year, so the Junos version and exam code are the reliable identifiers to check when you compare study materials.

Where It Sits in the Juniper Service Provider Track

JNCIP-SP is the middle professional rung of the service provider track. It builds on the specialist level and sits below the expert-level lab credential. The prerequisite is an active JNCIS-SP. Note the word "active": a lapsed prerequisite does not satisfy the requirement.

Juniper's program FAQ allows written exams to be taken in any order, but every prerequisite certification requirement must still be fulfilled and none is waived. Taking an exam out of sequence does not make you eligible to receive the credential. The full eligibility picture is covered in JNCIP-SP Requirements: Eligibility, Prerequisites & How to Qualify.

No additional mandatory education, work-experience hours, training hours, or references are stated on the credential overview. Recommended training exists but is optional.

Exam Facts: JN0-664 at a Glance

A few points deserve emphasis. The passing score is not a fixed percentage you can memorize; it is set statistically for the exam and reported to you. Anyone quoting a precise cutoff is likely borrowing it from somewhere else. See JNCIP-SP Passing Score for how to think about this. Likewise, the issuer publishes no percentage weights for the objective areas, so be skeptical of any site that claims to know how many questions come from BGP versus multicast.

The Seven Objective Areas

The official overview lists seven objective headings. Each pairs "describe concepts, operation or functionality" with a "given a scenario, demonstrate configuration or monitoring knowledge" requirement. The ordering below follows the issuer's list, not any weighting. For a deeper walkthrough, read JNCIP-SP Exam Domains: Complete Guide to All 7 Content Areas.

Some competitors add extra top-level MPLS or traffic-engineering headings. Those are not part of the official seven-domain hierarchy, and you should not treat them as extra exam domains.

Two Terminology Quirks in the Official Overview

The official overview contains two expansions that do not match standard Juniper technical documentation, and learners sometimes get confused by them.

• IS-IS flooding: the overview expands the IS-IS "LSP" abbreviation as "Label-switched path." In IS-IS, LSP refers to link-state PDUs, the units that IS-IS floods. Juniper's IS-IS documentation describes flooded link-state PDUs.
• PIM: the overview expands PIM as "Physical Interface Module." In multicast, PIM is Protocol Independent Multicast, as Juniper's PIM documentation states.

Learn the technically correct meanings. The objective headings themselves still cover IS-IS flooding in multi-area networks and PIM dense and sparse mode, so the topics are real even though the expansions in the overview are wrong.

Registration, Fees, and Test Delivery

JN0-664 is delivered through Pearson VUE, either at a test center or by OnVUE online proctoring, subject to availability, technical checks, and identification requirements. Your legal name must match your government-issued photo and signature identification, and the names on your CertMetrics and Pearson VUE accounts must be consistent. Mismatches are a common avoidable reason for being turned away.

The published examination fee is $400 USD per exam plus applicable taxes. No separate member and nonmember price is published. Final regional totals and any candidate-specific voucher discounts show at checkout, so confirm the amount there. Do not confuse the exam fee with training course charges or with the discount-voucher assessment. A full breakdown is in JNCIP-SP Certification Cost: Complete Pricing Breakdown, and scheduling details are in JNCIP-SP Exam Dates.

A passing result remains provisional pending security validation. Under the published policy, valid results appear in CertMetrics within three business days.

Look-Alike Pages That Are Not the Exam

Juniper's learning portal hosts several JNCIP-SP-related items that are easy to mistake for exam facts. Keep them distinct:

• The voucher assessment test: lists 80 minutes, three attempts, and a 70% threshold in order to earn a discount voucher. These are not JN0-664's timer, pass mark, or retake policy. Its 30-day voucher-use window is also unrelated to certification validity.
• The official practice test page: publishes a 70% practice threshold that explicitly does not establish the live passing score.
• Open Learning course access: a course, not the examination. Its introductory text is inconsistent with the advanced professional overview, so it should not replace the objective list.
• Specialist links: a shared portal link sometimes resolves to a Data Center specialist credential rather than JNCIP-SP, so verify any link before trusting it.

Validity, Renewal, and Retakes

The credential is valid for three years. You can renew by passing an eligible current exam, completing a specified qualifying course before expiry, or earning a higher-level certification in the same track. Qualifying higher-level activity also renews lower active same-track credentials and active associate certifications. No universal CEU or CPE quota is published by the reviewed policy. If a certification expires, you must restart the track.

The written-exam retake rules are:

1. No waiting period after a first failure.
2. A 14-calendar-day wait after a second or subsequent failure, counted from the day after the failed attempt.
3. At least 18 months before repeating an exam you have already passed.

Who Should Pursue It, and Who Hires for It

The natural audience is a networking professional who already holds JNCIS-SP and works on or toward carrier, ISP, or large provider backbone networks. The topic mix reflects that world: IGP design with OSPF and IS-IS, BGP at scale with route reflection, CoS for mixed traffic, multicast delivery, and the MPLS-based VPN services providers sell to enterprises.

Likely employers are those running Junos-based routing platforms: telecommunications carriers, ISPs, cloud and hosting networks, managed-network providers, and system integrators that build for them. Roles such as network engineer, backbone or core engineer, and service provider architect are typical matches. We do not have a verified salary figure restricted to JNCIP-SP holders, so we avoid quoting one; read JNCIP-SP Salary Guide and JNCIP-SP Jobs for context, and Is the JNCIP-SP Certification Worth It? for a value assessment. The same caution applies to pass-rate claims; see JNCIP-SP Pass Rate and How Hard Is the JNCIP-SP Exam? for what can and cannot be said.

Sequencing Your Preparation

Because no domain weights are published, sequence by dependency rather than by assumed exam emphasis. Learners in public forums frequently report CoS, multicast, IS-IS, and VPLS as weaker spots, so give those extra repetition. A full plan lives in the JNCIP-SP Study Guide; this is a sketch of the ordering logic only.

Juniper's recommended training for this exam is Advanced Junos Service Provider Routing, Junos Layer 2 VPNs, and Junos Layer 3 VPNs. These are optional, and attending them does not guarantee a pass. For compact last-pass review, a one-page JNCIP-SP cheat sheet helps, and the JNCIP-SP training overview covers course options. Independent practice questions, including those at our practice test site, support knowledge preparation only and are never actual exam questions.
