The Short Answer: Decoding the Acronym
JNCIP-SP stands for Juniper Networks Certified Professional, Service Provider Routing and Switching. It is the professional-level credential in Juniper's service provider routing and switching track, aimed at networking professionals who already have advanced Junos routing and switching knowledge. Juniper Networks governs the program, and its current certification pages carry HPE Juniper Networking branding following the company's integration into HPE.
That is the whole expansion, but the name carries more information than most acronyms. Each piece tells you something about the audience, the technology focus and the level of difficulty. If you want a broader definition of the credential beyond the acronym, our companion pages on what JNCIP-SP is and the JNCIP-SP meaning cover the same ground from different angles, and the JNCIP-SP certification overview collects the essentials in one place.
Reading the Name Letter by Letter
Breaking the acronym apart makes it easy to remember and to explain to a recruiter or manager.
| Letter(s) | Meaning | What it tells you |
|---|---|---|
| JN | Juniper Networks | The vendor and issuing body of the credential |
| C | Certified | Earned by passing a proctored written examination |
| I | Internet (in Juniper's naming scheme) | Part of the long-running JNCI* family of Juniper certifications |
| P | Professional | The advanced tier, above the specialist level |
| SP | Service Provider Routing and Switching | The track: carrier-scale routing, CoS, multicast and VPN services |
The practical takeaway is the two ends of the name. "Professional" places it above the associate and specialist rungs, and "Service Provider Routing and Switching" tells you the content is about carrier-grade networks, not campus or data center design.
Where the Professional Level Sits in the Track
The "P" in JNCIP is a position, not a decoration. Within the service provider routing and switching track, the professional credential builds on the specialist credential (JNCIS-SP). The exam you take for JNCIP-SP is JN0-664. It is not the expert-level hands-on lab examination, and it should not be confused with the voucher assessment or open-learning course pages that carry similar names.
If you are weighing whether the jump from specialist to professional is realistic for you, our difficulty guide discusses what makes this level a step up, and the requirements guide lays out eligibility in full.
What the Name Promises: The Seven Objective Headings
"Service Provider Routing and Switching" is a broad phrase, so it helps to know exactly what the issuer's objectives contain. The official overview lists seven headings. Juniper does not publish percentage weights for them, so no domain should be assumed to be heavier than another based on how many subtopics it lists.
Domain 1: OSPF
Concepts and operation of OSPFv2 and OSPFv3, 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, summarization and restriction
- Virtual links, OSPFv2 versus OSPFv3, and implementing OSPF routing policy
Domain 2: IS-IS
Areas and levels, designated intermediate system operation and the SPF algorithm.
- 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 deepest routing-protocol heading by sheer subtopic variety.
- Route selection, next-hop resolution, attributes, communities and regular expressions
- Multipath, multihop, load balancing, advanced options and route damping
- Flowspec and multiprotocol BGP
- BGP scaling through route reflection, and implementing BGP routing policy
Domain 4: Class of Service (CoS)
How Junos OS devices classify, queue and mark traffic.
- Processing on Junos OS devices, header fields, forwarding classes and classification
- Packet loss priority, policers, schedulers, drop profiles and rewrite rules
Domain 5: IP Multicast
Multicast addressing, traffic flow and the protocols that build distribution trees.
- Any-source multicast versus source-specific multicast, and RPF operation
- IGMP, PIM dense and sparse modes, and rendezvous-point operation, discovery and election
- SSM requirements, benefits and address ranges, and Anycast RP
Domain 6: Layer 3 VPNs
Provider-edge VPN services built on BGP and MPLS concepts.
- Full-mesh versus hub-and-spoke topologies, VPN-IPv4 addressing, route distinguishers and route targets
- Site of origin, sham links, VRF table-label, and next-generation multicast VPNs
- Scaling, IPv6 Layer 3 VPNs, Internet access options, and carrier-of-carriers or inter-provider models
Domain 7: Layer 2 VPNs
Four distinct technology branches that candidates must keep separate.
- BGP Layer 2 VPNs, with NLRI, route distinguishers and route targets
- LDP Layer 2 circuits, with virtual-circuit labels, autodiscovery and interworking
- VPLS, with BGP and LDP label distribution, multihoming and site IDs
- EVPN, with MAC learning and distribution, multihoming and BGP EVPN label distribution

Two Terminology Errors Hiding in the Official Overview
Anyone reading the official certification overview closely will notice two acronym expansions that look wrong. They are worth knowing about, because a name-focused article that ignored them would leave readers confused when they spot them.
- IS-IS LSP flooding: The overview expands "LSP" as "Label-switched path." In IS-IS, the flooded units are link-state PDUs, as Juniper's own IS-IS documentation states. This is a different use of the abbreviation LSP from the label-switched path you meet in MPLS.
- PIM: The overview expands multicast "PIM" as "Physical Interface Module." In multicast, PIM means Protocol Independent Multicast, which is how Juniper's multicast documentation defines it.
Acronym Look-Alikes and Pages That Are Not This Exam
Because several certification bodies use similar abbreviations, and because Juniper's own learning portal hosts multiple pages with near-identical names, it is easy to land on the wrong thing. The following are related but distinct:
- The voucher assessment test: A separate assessment tied to a discount voucher. Its own timing, attempt limit and threshold belong to that assessment and are not the rules of the live exam.
- The official practice test page: It publishes a 70% practice threshold, and that page explicitly does not establish the live passing score.
- Open Learning course access: A learning resource, not the examination. Its introductory text is inconsistent with the advanced professional credential overview, so it should not replace the official objectives.
- JNCIS-SP: The specialist-level credential that is the prerequisite. Specialist objectives are not the professional syllabus.
- Older exam codes: Legacy JN0-662/663 study material predates the current objectives, so check any guide against JN0-664.
One shared Juniper learning-portal link has been observed to resolve to the Data Center Specialist (JNCIS-DC) certification, not JNCIP-SP, so always confirm that a page names Service Provider Routing and Switching, Professional before trusting what it says.

A few details deserve emphasis. The fee table shows no member or nonmember distinction, and final regional checkout totals, taxes and any voucher discounts are determined at checkout. For a full breakdown, see our certification cost guide. The pass mark is not a flat number, so read our passing score explainer before relying on any figure you see elsewhere. Also note that a passing result is provisional until security validation completes, with valid results appearing in CertMetrics within three business days under the published policy.
Candidates who fail do not face a wait after a first failure, must wait 14 calendar days after a second or subsequent failure (counted from the day after the failed attempt), and must wait at least 18 months before repeating an exam they have already passed. Scheduling specifics are covered in our exam dates guide.
Why the Name Implies a Prerequisite
Professional-level credentials in the Juniper program build on what comes before them. For JNCIP-SP, the stated prerequisite is an active JNCIS-SP. The credential overview states no additional mandatory training hours, work-experience hours or references, and recommended training is optional.
Two clarifications trip people up. First, JNCIA-Junos is not the direct prerequisite for the professional exam. Second, the certification program FAQ allows written exams to be taken in any order, but every prerequisite requirement must still be fulfilled and none is waived, so exam-taking order is not the same as eligibility to receive the credential. A valid prerequisite must be active, so a lapsed JNCIS-SP is a problem worth resolving early. The requirements guide walks through the details.
Key Takeaway
Check the status of your JNCIS-SP in CertMetrics before you buy a study plan or schedule JN0-664. Also make sure the legal name on your accounts matches your government-issued photo identification, since Pearson VUE enforces that match at check-in.
Who the Credential Is Aimed At
The "Service Provider" half of the name points directly at the employers and roles where this knowledge is used: carriers, ISPs, managed-services providers and large organizations that run their own MPLS-based backbones. Typical work involves operating core and edge routing, delivering Layer 3 and Layer 2 VPN services to customers, applying CoS to protect sensitive traffic, and running multicast for content distribution.
No reliable salary figure specific to JNCIP-SP holders was verified, and general network-engineer pay data cannot honestly be relabeled as a JNCIP-SP number. If earnings are your main question, our salary guide explains what can and cannot be said, and the ROI analysis weighs the credential on broader terms. For the roles themselves, see our JNCIP-SP jobs page.
Turning the Name Into a Study Order
The seven objective headings fall into natural clusters, which makes the name a useful planning aid. Because no percentage weights are published, avoid allocating time by guesswork about which domain is "biggest." Instead, sequence by dependency.
Interior routing foundations
- OSPFv2/v3 area types, LSA flooding, DR/BDR operation and summarization
- IS-IS levels, wide metrics and route leaking, since both IGPs underpin the later VPN material
BGP and policy
- Route selection, communities, regular expressions and route reflection
- Routing policy practice across all three protocols
CoS and multicast
- Classifiers, forwarding classes, schedulers, drop profiles and rewrite rules
- RPF, PIM sparse mode, rendezvous points and SSM; learners often report these as common weak spots
VPN services
- Layer 3 VPN route distinguishers, route targets, sham links and MVPN
- Keep BGP Layer 2 VPNs, LDP circuits, VPLS and EVPN distinct in your notes
That plan is a starting frame, not a guarantee. Juniper's recommended optional courses are Advanced Junos Service Provider Routing, Junos Layer 2 VPNs and Junos Layer 3 VPNs; attending them does not ensure a pass. For a fuller preparation roadmap, read the JNCIP-SP study guide, and keep the one-page cheat sheet handy for review. When you are ready to test your recall, try our independently written questions on the JNCIP-SP practice test site. They are for knowledge preparation only and are not actual exam questions or an official mock exam.
