JNCIP-SP: Juniper Networks Certified Professional Service Provider Routing and Switching (JNCIP-SP)

About the JNCIP-SP Exam

Professional-level Juniper service provider certification on Junos OS - advanced OSPFv2/OSPFv3 and IS-IS link-state routing (area types, LSA/LSP flooding, DR/DIS, wide metrics, virtual links, route leaking), advanced BGP (path selection, next-hop resolution, communities, AS-path regular expressions, multipath, multihop, flap damping, BGP flowspec, multiprotocol BGP, route reflection and confederations), Class of Service (forwarding classes, BA and multifield classification, packet loss priority, policers, schedulers, drop profiles, rewrite rules), IP multicast (IGMP, PIM dense/sparse mode, RP discovery and election, anycast-RP with MSDP, SSM, RPF), Layer 3 VPNs (RFC 4364 MP-BGP VPN-IPv4, route distinguishers and route targets, VRF table-label, site of origin, sham links, NG-MVPN, IPv6 6VPE, carrier-of-carriers and inter-provider models), and Layer 2 VPNs (BGP/Kompella L2VPN, LDP/Martini L2 circuits, BGP-VPLS and LDP-VPLS, and EVPN with multihoming).

250 original practice questions for the Juniper Networks Certified Professional Service Provider Routing and Switching (JNCIP-SP, exam JN0-664). Covers OSPFv2 and OSPFv3 (area types including stub/totally-stubby/NSSA, LSA flooding, DR/BDR election, SPF and external metric types, route summarization and virtual links), IS-IS (Level 1/Level 2 areas, LSP flooding, DIS election, wide metrics, route summarization and route leaking), advanced BGP (the Junos route-selection process, next-hop resolution, attributes and communities, AS-path regular expressions, multipath, multihop, flap damping, BGP flowspec, multiprotocol BGP, and scaling with route reflection and confederations), Class of Service (the Junos CoS processing model, forwarding classes, behavior-aggregate and multifield classification, packet loss priority, single-rate and two-rate tricolor policers, schedulers and scheduler-maps, RED/WRED drop profiles, and rewrite rules), IP multicast (multicast addressing, ASM vs SSM, reverse path forwarding, IGMP, PIM dense and sparse mode, rendezvous-point discovery and election, anycast-RP with MSDP, and SSM), Layer 3 VPNs (RFC 4364 control and data planes with a two-label stack, route distinguishers and route targets, VRF table-label, site of origin, OSPF sham links, next-generation multicast VPNs, IPv6 Layer 3 VPNs, and carrier-of-carriers and inter-provider Option A/B/C models), and Layer 2 VPNs (BGP/Kompella Layer 2 VPNs, LDP/Martini Layer 2 circuits, BGP-VPLS and LDP-VPLS, and EVPN with MAC learning and multihoming). Each question is a realistic Junos OS service-provider scenario on MX, PTX, and ACX platforms with a named character, a detailed explanation, and per-option rationale.

Who Should Take This Exam?

The JNCIP-SP is designed for experienced network engineers who design, deploy, and troubleshoot advanced Juniper MX, PTX, and ACX service-provider and carrier networks. It is the professional tier above JNCIS-SP, so a solid command of OSPF, IS-IS, BGP, and MPLS on Junos is assumed — the exam goes deep on MPLS-based Layer 3 and Layer 2 VPNs (L3VPN, L2VPN/Kompella, VPLS, EVPN), IP multicast, and Class of Service.

Prerequisites: JNCIS-SP (JN0-363)

Typical study time: 8-12 weeks of focused study

Exam Quick Facts

Exam Domains & Weights

The JNCIP-SP exam covers 7 domains. Focus your study time based on the weights below — higher-weighted domains have more exam questions.

💡 Study tip: Layer 2 VPNs (21%) and Layer 3 VPNs (18%) are the heaviest areas — the MPLS-based VPN content is the heart of JNCIP-SP, so make sure you can reason about the L3VPN two-label stack, route distinguishers vs route targets, Kompella vs Martini L2VPNs, and BGP-VPLS vs LDP-VPLS vs EVPN signaling. Juniper does not publish official percentage weights for JN0-664, so treat these as study guidance based on objective breadth: give every domain real time, because exam questions can come from any of the seven.
