The JN0-664 exam is the professional-level exam for the Service Provider Routing and Switching (JNCIP-SP) certification. It tests your understanding of advanced routing technologies and your ability to configure, monitor, and troubleshoot service provider networks running Junos OS.
If you already work with OSPF, IS-IS, BGP, and VPN services, this page will help you identify what to review before scheduling the exam.

JN0-664 Exam Objectives
The official outline contains seven objective areas. The table below gives a brief view of each one; it does not assign unofficial weights.
| Objective Area | Main Focus |
|---|---|
| OSPF | OSPFv2 and OSPFv3 operation, areas, LSAs, metrics, route control, and monitoring. |
| IS-IS | Levels and areas, LSP flooding, metrics, route leaking, routing policy, and monitoring. |
| BGP | Route selection, attributes, communities, next-hop resolution, scaling, multiprotocol BGP, and policy. |
| Class of Service (CoS) | Classification, forwarding classes, packet loss priority, policers, schedulers, and rewrite rules. |
| IP Multicast | Multicast traffic flow, RPF, IGMP, PIM, rendezvous points, ASM, and SSM. |
| Layer 3 VPNs | VPN routing and traffic flow, route distinguishers, route targets, VRFs, MVPNs, and scaling. |
| Layer 2 VPNs | BGP Layer 2 VPNs, LDP Layer 2 circuits, VPLS, EVPN, and related troubleshooting. |
What to Focus on During Preparation
Do more than memorize protocol definitions. The outline repeatedly asks you to apply concepts to configuration, monitoring, and troubleshooting scenarios. Practice reading Junos output and explaining what a route, label, or policy will actually do.
- Routing behavior: Compare OSPF and IS-IS area behavior, then review BGP path selection and next-hop resolution.
- VPN control and data planes: Be clear about the different jobs of route distinguishers, route targets, and labels.
- Operational verification: Use lab exercises to check whether the observed routing or forwarding state matches your intended design.
A common preparation mistake is treating EVPN, VPLS, and Layer 3 VPNs as interchangeable “VPN topics.” Their signaling and forwarding models differ, and scenario questions may depend on that distinction.

JN0-664 FAQ
Is hands-on Junos experience important for this exam?
Yes. Several objectives go beyond identifying terms and ask you to interpret configuration, monitoring, or troubleshooting scenarios. Lab work is particularly useful for routing policy and VPN verification.
Which Juniper training courses match the exam?
Juniper recommends Advanced Junos Service Provider Routing, Junos Layer 2 VPNs, and Junos Layer 3 VPNs. These are preparation resources, not a guarantee of passing.
How long is the JNCIP-SP certification valid?
Juniper states that its certifications are valid for three years. Check the current recertification rules before your certification expires.
