SEGRTE201 Training for Your Team — Implementing Segment Routing on Cisco IOS XR
Segment routing is the rare technology shift with an unglamorous, compelling case: fewer protocols to run, fast reroute that computes itself, and traffic engineering without per-flow state rotting in the core. The hard part is not the concept — it is migrating a live MPLS backbone to it. SEGRTE201 (Implementing Segment Routing on Cisco IOS XR) is built around exactly that: SR-MPLS mechanics and IGP extensions, coexistence with LDP, staged migration, SR-TE policies, TI-LFA protection, and an honest orientation on SRv6.
The course fits teams at the decision or execution stage of an SR project — providers retiring LDP and RSVP-TE, and large enterprises whose self-run MPLS cores are heading the same way. It assumes MPLS fluency and IOS XR familiarity, and spends its time where the risk lives: the transition.
We organize delivery through authorized partners with instructors who have run SR migrations in production — live online in your time zone, on site, or as a private group with the lab weighted toward your migration scenario.
Who this course is for
- Backbone engineers planning or executing an LDP/RSVP-to-SR migration
- Provider architects designing traffic engineering on segment routing
- Senior enterprise engineers running MPLS cores headed the same direction
- Engineers preparing for SP roles where SR is already the default transport
What your team will learn
Topic areas below are grouped in our own words. The full official agenda is available on request — it comes from the authorized partner as part of your quote.
- Segment routing from first principles: why the industry is retiring LDP and RSVP-TE
- SR-MPLS in practice — segments, SIDs and the IGP extensions that carry them
- Migrating a live MPLS network to SR without customers noticing
- Traffic engineering with SR policies: intent-based paths without per-flow state in the core
- TI-LFA fast reroute — sub-50ms protection that computes itself
- SRv6 orientation: where segment routing over IPv6 fits and when to care

SEGRTE201 vs alternatives: which to choose
Factual criteria only — level, duration, audience and certification. The right choice depends on your team's starting point and stack.
Cisco MPLS (Implementing Cisco MPLS)
The classic course on MPLS foundations — labels, LDP, VPN transport. Choose MPLS if the team still needs those fundamentals; SEGRTE201 assumes them and teaches the modern replacement for the label distribution and TE machinery.
Cisco SPCOR (SP Core)
The CCNP Service Provider core covers segment routing as one topic within the full SP map. Choose SPCOR for certification and breadth; SEGRTE201 when SR is the project — a migration or TE design — and you need a focused deep dive.
A custom intensive
Mid-migration already? A custom program can rehearse your specific cutover — coexistence with LDP, SR policy design, TI-LFA verification — on a lab modeled after your backbone topology.
Need only part of SEGRTE201?
If your team needs a subset of this program — or a mix of topics from several courses — we build a custom 2–4 day intensive on our own materials, shaped by your infrastructure. One custom program typically replaces 2–3 catalog courses.
Explore custom coursesSEGRTE201: frequently asked questions
Do we need MPLS experience before a segment routing course?
Yes, for this course: SEGRTE201 constantly contrasts SR with LDP and RSVP-TE, and the migration content assumes you operate what you are migrating from. Teams without MPLS grounding should take the MPLS course first; we can plan the pair as a sequence.
Does the course cover SRv6 or only SR-MPLS?
The implementation depth is on SR-MPLS, which is what most production migrations deploy today. SRv6 is covered at orientation level — architecture, use cases, maturity — so teams can make an informed roadmap decision rather than a fashionable one.
Is segment routing relevant outside service providers?
Increasingly: large enterprises with self-operated MPLS cores — banks, utilities, research networks — adopt SR for the same reasons providers do: less protocol machinery, TI-LFA protection, cleaner traffic engineering. The course applies directly to those environments.
Can our team learn SR migration without risking the production network?
That is the design of the course: the lab walks through SR activation alongside LDP, coexistence, and staged traffic migration on IOS XR routers. Engineers make the mistakes in the lab week, not in your maintenance windows.
