ExploreAbout this exam
The Nokia BGP for Internet Routing exam validates practical command of BGP as deployed on Nokia Service Router platforms and in internet-scale routing. It suits network engineers, service-provider operations staff, and design or escalation engineers who already understand IP routing and now need to prove they can build sessions, steer traffic with policy, scale an autonomous system, and defend the routing table. The blueprint spans BGP fundamentals and message types, session establishment and neighbor configuration, the best-path decision process, attributes and policy control, scaling and convergence with route reflectors, confederations and timers, internet multihoming and traffic engineering, security and route filtering, IPv6 and multi-address-family operation, and SR OS implementation and troubleshooting. Expect multiple-choice questions that mix protocol theory with configuration reasoning and scenario diagnosis, so memorising attribute lists is not enough; you should be able to explain why a particular route wins or why a session stays idle. Prepare by labbing SR OS BGP configuration end to end, reading Nokia's own documentation for the software release you use, and practising prefix-list, AS-path and community policy on real or virtual routers. Confirm current administrative details with Nokia, as this independent guide is not affiliated with or endorsed by Nokia.
What you'll study
About Nokia BGP for Internet Routing preparation
What is the exam format?
It is delivered as multiple-choice questions covering the nine blueprint domains. The official body publishes the current number of questions, time allowance, and delivery options, so check Nokia's certification pages for the authoritative format rather than relying on second-hand figures.
How difficult is it?
It assumes working routing knowledge, not beginner status. Questions often describe a topology or configuration and ask for the outcome, so candidates who only memorised attribute order struggle. Hands-on SR OS experience and the ability to reason through a session or path-selection problem matter more than recall.
What happens if I fail, and can I retake?
Retake rules, waiting periods, and any fees are set by Nokia and can change. Check the official certification site for the current retake policy before scheduling. Build a study plan that targets your weakest domains from the score report rather than simply rebooking immediately.
How long should I plan to study?
Most working engineers need several weeks of focused effort, weighted toward best-path selection, policy, and scaling, which carry the most blueprint weight. If SR OS is new to you, add lab time to become fluent in neighbor configuration, address families, and troubleshooting commands before attempting the exam.
In what order should I study the domains?
Start with fundamentals and session establishment so later topics have context, then best-path and attributes together, since policy only makes sense against the decision process. Move to scaling, multihoming, and security, and finish with IPv6 address families and SR OS troubleshooting, revisiting weak areas through labs.
Which topics cause the most failures?
Common trouble spots are the exact tie-breaking order in best-path selection, the difference between local preference and MED scope, and why a route reflector or confederation changes next-hop and loop-prevention behaviour. Filtering questions also catch candidates who confuse prefix length matching with AS-path regular expressions.
Do I need lab equipment?
You need access to SR OS, either through virtual routers, a lab, or a simulator, to answer configuration and troubleshooting questions confidently. Reading alone rarely builds the intuition for session states, address-family negotiation, and policy application order that scenario questions demand.
