- The exam is 65 multiple-choice questions in 90 minutes, delivered through Pearson VUE, at a published base fee of $400.
- An active JNCIS-SP is the required prerequisite; JNCIA-Junos does not substitute for it.
- Juniper lists seven objective headings, from OSPF through Layer 2 VPNs, and publishes no percentage weights.
Breaking Down the Acronym
If you have landed on this page wondering what JNCIP-SP means, the short answer is that every letter carries information. Read left to right, the acronym is a compact description of the vendor, the credential level, and the technology track:
- JN is the Juniper Networks prefix used across the company's certification family.
- C stands for Certified.
- I stands for Internet. Juniper's credential names have long used "Internet" in this slot, and it carries no special weight beyond identifying the program.
- P stands for Professional, which is the level indicator.
- SP stands for Service Provider Routing and Switching, which is the track.
Put together, JNCIP-SP is shorthand for Juniper Networks Certified Professional, Service Provider Routing and Switching. Several other credentials elsewhere in the industry happen to share a similar-looking acronym, so it is worth being precise: everything on this page concerns the Juniper credential and nothing else. For related phrasing of the same question, see our pages on what JNCIP-SP stands for and the broader explanation of the certification.
Which JNCIP-SP This Is
The credential is issued by Juniper Networks, whose current certification pages carry HPE Juniper Networking branding following the HPE acquisition. It is aimed at networking professionals who already have advanced Junos routing and switching knowledge and want to demonstrate that depth in a service provider context. Testing is administered by Pearson VUE, either at a test center or through OnVUE remote delivery, subject to availability, technical checks and identification requirements.
For a fuller treatment of how this certification fits the wider Juniper program, our JNCIP-SP certification overview and the page on what JNCIP-SP is cover the ground from different angles.
What "Professional" Signals in Juniper's Track
Juniper's service provider track is tiered. The associate level establishes Junos fundamentals, the specialist level (JNCIS-SP) covers core service provider routing and switching, and the professional level, JNCIP-SP, goes deeper and wider. The word "Professional" here is a statement about scope: the exam expects you to reason about interactions between protocols, not just recite how one protocol behaves in isolation.
That shows up in the objective wording. Each domain pairs a "describe concepts, operation or functionality" requirement with a "given a scenario, demonstrate configuration or monitoring knowledge" requirement. In the Layer 2 VPN domain, the scenario requirement explicitly extends to troubleshooting. These are written-exam knowledge objectives, though. JN0-664 is a multiple-choice test of what you know, not a live lab, and it is not the expert-level hands-on examination.
The Exam Behind the Letters: JN0-664
The logistics for the live exam are straightforward and worth keeping separate from other Juniper assessments you may encounter during preparation.
| Item | JN0-664 detail |
|---|---|
| Questions | 65 |
| Time allowed | 90 minutes |
| Format | English-language written multiple-choice examination |
| Delivery | Pearson VUE test center or OnVUE remote, subject to availability and checks |
| Published base fee | $400 USD per examination, plus applicable taxes |
| Passing score | Set statistically for the exam and reported to the candidate |
| Software version | Junos OS 22.3 |
Two points deserve emphasis. First, the passing score is not a published fixed percentage. You will see third-party sites quote a numeric cutoff; the issuer overview does not support that. Our page on the JNCIP-SP passing score goes into what is and is not known. Second, the $400 figure is the verified base fee. Taxes, regional checkout totals and any candidate-specific discounts depend on your checkout, so confirm the final amount in the Pearson VUE flow. The full picture is in our JNCIP-SP certification cost breakdown.
The Seven Objective Areas in Plain Language
Juniper's overview lists seven objective headings. No percentage weights are published, so you cannot responsibly claim that any one area is "worth" a set share of the exam. What you can do is understand what each heading asks of you. Our complete guide to all seven content areas goes further; here is the orientation.
Domain 1: OSPF
Covers OSPFv2 and OSPFv3 concepts and operation, plus scenario-based configuration and monitoring.
- Area types and operations, and LSA flooding across multiple areas
- Designated and backup designated router operation, and the SPF algorithm
- Metrics including external metric types, route summarization and restriction, virtual links
- OSPFv2 versus OSPFv3, and implementing OSPF routing policy
Domain 2: IS-IS
The IS-IS counterpart to OSPF, with its own vocabulary and design behaviors.
- Areas and levels, flooding through multi-area networks, designated intermediate system operation
- SPF algorithm and metrics including wide metrics
- Route summarization and route leaking
- Single-area and multi-area configuration and monitoring, including IS-IS routing policy
Domain 3: BGP
The broadest routing domain, mixing path-selection theory with operational features.
- Route selection, next-hop resolution, attributes, communities and regular expressions
- Multipath, multihop, load balancing, route damping, flowspec and multiprotocol BGP
- BGP scaling through route reflection, described as a separate requirement
- Configuration and monitoring scenarios, including BGP routing policy
Domain 4: Class of Service (CoS)
How Junos OS devices classify, queue and mark traffic.
- Processing on Junos devices, header fields, forwarding classes and classification
- Packet loss priority, policers, schedulers, drop profiles and rewrite rules
- Scenario-based configuration and monitoring
Domain 5: IP Multicast
Multicast fundamentals through to policy.
- Addressing, traffic flow, any-source multicast versus source-specific multicast, and RPF operation
- IGMP, PIM dense and sparse modes, rendezvous point concepts, discovery and election
- SSM requirements, benefits and address ranges, and Anycast RP
- Configuration and monitoring for IGMP and PIM, plus IP multicast routing policy
Domain 6: Layer 3 VPNs
The service provider VPN heart of the exam.
- Control and data plane flow, full-mesh versus hub-and-spoke, VPN-IPv4 addressing
- Route distinguishers, route targets, route distribution, site of origin, sham links, VRF table-label
- Next-generation multicast VPNs, IPv6 Layer 3 VPNs, scaling and Internet access options
- Carrier-of-carriers and inter-provider VPN models, described separately
Domain 7: Layer 2 VPNs
Four distinct technology branches, each described separately.
- BGP Layer 2 VPNs: forwarding tables, connection mapping, NLRI, route distinguishers and targets, scaling
- LDP Layer 2 circuits: virtual-circuit label, autodiscovery, Layer 2 interworking
- VPLS: BGP and LDP label distribution, route targets, multihoming, site IDs
- EVPN: MAC learning and distribution, multihoming, BGP EVPN label distribution
One note on completeness: this hierarchy is exactly what the issuer lists. Some third-party resources add extra top-level MPLS or traffic-engineering headings. Those are not official JN0-664 domains, so do not let them reshape your plan.
Two Terminology Errors in the Official Overview
A detail that sets careful candidates apart: the pinned overview contains two expansions that are technically wrong, and it is useful to know the correct versions so they do not confuse your study.
- IS-IS flooding. The overview expands "LSP" as "Label-switched path." In IS-IS, flooded LSPs are link-state PDUs, as Juniper's own IS-IS documentation describes. They have nothing to do with MPLS label-switched paths.
- PIM. The overview expands "PIM" as "Physical Interface Module." In multicast, PIM is Protocol Independent Multicast, as Juniper's PIM documentation states. The topic being tested is multicast routing, not hardware.
Key Takeaway
Learn the technically correct expansions (link-state PDUs and Protocol Independent Multicast) and study the real protocols. The official wording discrepancy does not change what the underlying objectives test.
What the Credential Requires and How Long It Lasts
The prerequisite certification is an active JNCIS-SP. JNCIA-Junos is not the direct prerequisite, and specialist objectives are not the professional syllabus. The credential overview states no additional mandatory education, work-experience hours, training hours or references, and recommended training is optional. Juniper's General Certification Program FAQs allow written exams to be taken in any order, but every prerequisite requirement must still be fulfilled and none is waived, so taking an exam early is not the same as being eligible to receive the credential. Our JNCIP-SP requirements page walks through eligibility in detail.
Once earned, the certification is valid for three years. You can renew by passing an eligible current exam or completing a specified qualifying course before expiry, or by obtaining 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, and an expired certification means restarting the track.
Retake rules for the written exam are also defined:
- No waiting period after a first failure.
- 14 calendar days after a second or subsequent failure, counted from the day after the failed attempt.
- At least 18 months before repeating an exam you have already passed.
Practical registration details: your legal name must match your government-issued photo and signature identification and your CertMetrics and Pearson VUE accounts. A passing score is provisional pending security validation, and valid results appear in CertMetrics within three business days under the published policy. For scheduling specifics, see JNCIP-SP exam dates.
Who Holds It and Where It Gets Used
The credential is built for engineers who operate or design provider-style networks on Junos: carrier backbones, ISP cores, wholesale and enterprise VPN services, and the large campus or data center interconnects that borrow service provider techniques. The seven domains map directly onto daily provider work. IGP design (OSPF and IS-IS) underpins the core, BGP handles peering and scale, CoS governs how services share capacity, multicast supports video and distribution workloads, and Layer 3 and Layer 2 VPNs are the revenue-bearing services themselves.
Typical roles where that skill set is relevant include network engineer, senior network engineer and network architect positions at providers, integrators and large operators running Junos platforms. Our JNCIP-SP jobs page explores this further. On pay, be careful: no reliable current salary figure restricted to JNCIP-SP holders has been verified, and generic network engineer ranges should not be relabeled as a JNCIP-SP premium. The salary guide and the ROI analysis discuss how to evaluate the investment without false precision.
Things People Mix Up With JNCIP-SP
| Often confused with | Why it is different |
|---|---|
| JNCIS-SP | The specialist-level credential and the required prerequisite; it uses a different objective set and Junos version. |
| JNCIA-Junos | An associate-level credential; not the direct prerequisite for JNCIP-SP. |
| The voucher assessment test | A separate discount-voucher assessment with its own timer, attempts and 70% threshold; not the live exam. |
| Open Learning course access | Course material, not the examination itself. |
| Expert-level lab exam | JN0-664 is a written multiple-choice exam, not a hands-on lab. |
| Cisco professional-level tracks | Comparison headlines do not establish equivalence; objectives and logistics differ. |
Learners often ask how this compares in difficulty to other professional-level exams. Honest answers are subjective: community discussions consistently single out CoS, multicast, IS-IS and VPLS as areas where candidates feel under-prepared, but those are experience reports, not official difficulty scores. See how hard the JNCIP-SP exam is and the pass rate discussion, which explains why no verified population pass rate is available.
Mapping the Domains Onto a Study Calendar
Study method matters less than sequencing. Because the domains build on each other, the order below puts prerequisite concepts first. Adjust the pacing to your own experience; this is a template, not a promise of readiness.
IGPs: OSPF and IS-IS
- Compare area types against IS-IS levels side by side
- Practice route summarization, route leaking and policy scenarios
BGP in depth
- Route selection, communities, regular expressions, route reflection
- Flowspec, multiprotocol BGP and damping, since later VPN domains depend on them
Class of Service and IP Multicast
- Classification through rewrite rules in one pass
- RPF, PIM sparse mode, SSM and Anycast RP
Layer 3 VPNs, then Layer 2 VPNs
- RDs, RTs, site of origin, sham links, MVPN, carrier-of-carriers
- Keep BGP L2VPN, LDP circuits, VPLS and EVPN distinct in your notes
The reasoning: VPN domains lean on BGP and an underlying IGP, so leaving them for last lets earlier material do double duty. Recommended optional training named in the overview includes Advanced Junos Service Provider Routing, Junos Layer 2 VPNs and Junos Layer 3 VPNs, though attending a course does not guarantee a pass. Use independent practice questions to find weak spots, and for structure see our JNCIP-SP study guide and one-page cheat sheet. When you are ready to test yourself on the written format, the JNCIP-SP practice test site offers independently authored questions for knowledge preparation. They are not recalled exam questions and do not measure hands-on competence. For course-oriented options, see JNCIP-SP training.
