Juniper JNCIP-SP: Service Provider Routing and Switching Professional (JN0-664)

Service provider networks fail in costly ways when the engineers running them only know the basics. A misplaced route reflector, a poorly planned VPLS design, or unchecked LSDB flooding can turn a routine change into a customer-facing outage. This course helps IT Directors and Team Leads close that gap across OSPF, IS-IS, BGP, advanced multicast routing, Class of Service on Junos, MPLS L3VPN and L2VPN, VPLS, and EVPN-MPLS.

Role fit: This course is for network engineers with three to five years of infrastructure experience. It is not an onboarding course for junior staff. It also prepares engineers for JN0-664, the one exam required for JNCIP-SP.

Time investment: Plan for roughly 32 hours of video across 28 skills, plus lab practice time. Most skills run about an hour, so engineers can fit them into weekly study blocks without long stretches away from operations.

Change-management notes: The skills build on each other. For example, the LDP-signaled VPLS videos assume commands configured in the earlier BGP VPLS videos. Assign the skills in order. The trainer stresses planning and design before anyone touches the CLI, which supports safer change practices in production.

How CBT Nuggets supports the outcome: The course is structured as a sequential Playlist, so Training Managers can assign it as one path. The trainer also encourages hands-on repetition using Juniper-hosted virtual labs or physical gear. That way engineers practice deployments and validation commands before applying them on live networks.

Service provider teams rarely fail on the basics. They fail on the edge cases: a link drop that causes suboptimal routing between area border routers, an iBGP mesh that no longer scales, or a redundant customer connection that turns into a forwarding problem. This training prepares network engineers for those situations on Junos.

• Fewer routing surprises after changes or acquisitions. Engineers learn to read and protect the OSPF and IS-IS link-state databases, limit excessive flooding when something goes wrong, and use designs such as multi-area single adjacency to prevent suboptimal routing when a link fails.
• iBGP that scales with the network. The course covers route reflector placement, full mesh route reflector cores, and confederations. It also teaches advanced BGP attribute manipulation and policy controls, so teams can grow the core without constant redesign.
• Faster, more consistent customer service delivery. Teams learn to build the backbone with IGP, MPLS, and multiprotocol BGP, then deploy and tune MPLS L3VPNs, BGP L2VPN-based VPLS, and EVPN-MPLS for customer requirements.
• Resilient multi-homed sites. Engineers work through VPLS multi-homing with BGP and LDP so that service fails over quickly when a primary provider edge goes down.

Throughout the course, the instructor stresses planning before typing commands and validating results with show commands. That habit reduces configuration errors in production and shortens troubleshooting time.

Knowledge

• How the OSPF and IS-IS link-state databases are built and read, including LSAs, TLVs, SPF behavior, wide metrics, and the overload bit
• How BGP attributes, communities, and policy drive path selection, and how route reflectors and confederations solve iBGP scale problems
• How advanced BGP manipulation and policy support large enterprise and service provider routing operations
• How IGMP and PIM deployment options shape multicast routing behavior on Junos
• How an MPLS backbone (IGP, MPLS, and multiprotocol BGP) carries L3VPN, NG-MVPN, L2VPN, Layer 2 circuit, and VPLS services
• How EVPN NLRI route types support scalable, multi-homed Layer 2 services over MPLS

Ability

• Validate and troubleshoot OSPF and IS-IS adjacencies and LSDB contents with Junos show commands, and protect the LSDB from excessive flooding
• Fix suboptimal OSPF routing with multi-area single adjacency, and apply route redistribution, leaking, and summarization in IS-IS
• Write practical regex for AS paths and build BGP policies that manipulate attributes and communities
• Place route reflectors to fit the network design and confirm that routes propagate as intended
• Deploy and customize MPLS L3VPNs, BGP L2VPNs, LDP Layer 2 circuits, and BGP- or LDP-signaled VPLS, including multi-homing for fast failover
• Plan and deploy EVPN-MPLS on Junos, including an anycast default gateway
