Nokia NRS I study plan

Nokia NRS I · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

IP routing fundamentals and Nokia IP network routing, switching and aggregation

  • Explain, in your own words, how longest-prefix match and administrative distance interact when a Nokia router chooses among competing routes

  • Configure and verify OSPFv2 areas, interface costs, and passive interfaces on a simulated SR-series or 7750 SR node

  • Trace a multi-area OSPF topology and predict which router becomes ABR and where Type 3 LSAs are generated

  • Build a one-page diagram mapping the Nokia SR OS routing table fields (preference, metric, next-hop, protocol) to their decision role

Your checkpoint

A working two-area OSPF lab with three routers plus a written route-selection walkthrough showing at least five competing-prefix scenarios and the winning route for each

Week 2

IP routing fundamentals and Nokia IP network routing, switching and aggregation

  • Configure IS-IS levels, wide metrics, and level-2 summarization in a lab and confirm adjacency states

  • Compare OSPF and IS-IS convergence behavior and document where each is typically deployed in Nokia IP aggregation designs

  • Configure BGP peering with an eBGP neighbor and an iBGP full mesh, applying next-hop-self and route reflectors where appropriate

  • Manipulate path selection using local-preference, AS-path prepending, and MED, and verify each outcome

Your checkpoint

A BGP lab with two autonomous systems and a route-reflector cluster, plus a table of ten prefixes showing the chosen best path and the attribute that decided it

Week 3

IP routing fundamentals and Nokia IP network routing, switching and aggregation

  • Configure LDP and RSVP-TE signaled LSPs on Nokia routers and verify label bindings and path state

  • Explain segment routing with MPLS and SRv6 encapsulation and configure a basic SR-ISIS topology

  • Design a two-tier aggregation and core topology with redundancy and summarize the failure domains

  • Configure LAG and MC-LAG between aggregation switches and verify failover with a link-down test

Your checkpoint

A documented aggregation design covering MPLS or SR transport, MC-LAG redundancy, and a written failover test log with observed convergence times

Week 4

IP network automation (Network Services Platform)

  • Describe the Nokia Network Services Platform architecture, including NSP discovery, NFM-P, and the intent-based controller components

  • Onboard a simulated router into NSP and confirm the managed-object inventory is complete

  • Create a service template and deploy an Epipe or VPLS service through the NSP workflow

  • Compare model-driven CLI and NETCONF/YANG workflows and identify which Nokia interfaces expose each

Your checkpoint

A screen-capture-free written runbook describing end-to-end service provisioning through NSP, from device onboarding to service verification, with the exact verification commands listed

Week 5

IP network automation (Network Services Platform)

  • Write a Python or Ansible script that pushes a configuration change to a Nokia router using the model-driven interface

  • Explain YANG model structure and identify the Nokia MD-CLI model paths for interface and service configuration

  • Use NSP telemetry and assurance functions to detect a simulated fault and correlate it to a configuration event

  • Design an idempotent configuration workflow that validates intent before and after deployment

Your checkpoint

A working automation script with a README that explains the YANG paths used, the validation steps, and the rollback procedure

Week 6

IP network security

  • Configure and verify control-plane protection filters that rate-limit traffic destined for the routing engine

  • Apply management-plane ACLs and confirm that unauthorized access attempts are dropped while legitimate sessions persist

  • Configure BGP prefix limits, RPKI-based origin validation, and TCP MD5 or authentication for peer sessions

  • Explain how uRPF and interface-level anti-spoofing mitigate source-address attacks on Nokia platforms

Your checkpoint

A security hardening checklist applied to a lab router, with before-and-after verification output summarized in text and a table mapping each control to the attack it mitigates

Week 7

IP network security & IP networks within data center and transport connectivity

  • Configure IPsec or MACsec protection for a transport link and verify encrypted traffic with operational commands

  • Describe EVPN-VXLAN data center fabric building blocks and configure a basic EVPN service on a leaf-spine simulation

  • Explain underlay and overlay separation, route types in EVPN, and how anycast gateway supports workload mobility

  • Compare data center fabric options and transport connectivity models for a given customer requirement

Your checkpoint

A design note comparing an EVPN-VXLAN data center fabric and an MPLS-based transport option, with a recommendation, the security controls applied to each, and verification steps

Week 8

IP routing fundamentals and Nokia IP network routing, switching and aggregation & IP network automation (Network Services Platform) & IP network security & IP networks within data center and transport connectivity

  • Re-run the full lab topology end to end and confirm every service, route, and security policy still behaves as documented

  • Take two timed practice sets weighted 25 percent per domain and review every wrong answer to its root cause

  • Rebuild the weakest two domain summaries from memory and correct gaps against your notes

  • Write a one-page exam-day reference of commands and concepts you most often forgot

Your checkpoint

A scored practice-set log showing per-domain accuracy, a list of corrected weak areas, and a final one-page reference sheet

Milestones

Week 2: Can configure OSPF, IS-IS, and BGP from a blank node and correctly predict route selection in ten scenarios without notes

Week 4: Can explain NSP architecture and provision a service through the platform workflow from memory, and has completed the routing lab with all failover tests passing

Week 6: Can deploy a configuration change through automation and pass a self-graded security hardening review of the lab router with all listed controls verified

Week 8: Achieves at least 80 percent on two timed mixed-domain practice sets and has a written remediation list for any remaining gaps
