The Service Provider Routing and Switching, Professional (JNCIP-SP) certification (JN0-664) is an advanced-level Juniper certification designed for experienced network engineers, architects, and service provider specialists who manage, optimize, and troubleshoot large-scale Juniper service provider networks. This course aligns with the official JN0-664 exam objectives and builds upon the concepts covered in JNCIS-SP (JN0-363), focusing on highly complex routing, MPLS, and VPN solutions for service provider environments.

This certification validates your expertise in advanced routing protocols, traffic engineering, VPN implementations, high availability solutions, and scalable network architectures. It is intended for professionals working on carrier-grade networks and serves as a stepping stone toward the expert-level JNCIE-SP certification.

Key topics include:

• Advanced routing protocols: deep-dive into BGP, IS-IS, and OSPF with scaling and optimization techniques

• MPLS traffic engineering: RSVP-TE, LSP prioritization, and bandwidth optimization strategies

• Layer 2 & Layer 3 VPNs: complex deployments of VPLS, VPWS, and L3VPNs across multi-tenant environments

• Segment routing & EVPN: leveraging modern technologies for high-performance network designs

• Class of Service (CoS): advanced queuing, traffic shaping, and congestion management for SLAs

• High availability features: Nonstop Routing (NSR), Graceful Restart (GR), and BFD for link stability

• Multicast in SP environments: configuring PIM, IGMP, and MSDP in large-scale deployments

• Monitoring, diagnostics & troubleshooting: analyzing control-plane behaviors and resolving packet forwarding issues
