ENSLD Training for Your Team — Designing Cisco Enterprise Networks
Most enterprise networks were never designed — they grew. A switch block added per office, a WAN link per acquisition, until the topology is something everyone operates and nobody can defend on a whiteboard. ENSLD (Designing Cisco Enterprise Networks) exists for the moment that stops being sustainable: a campus refresh, an SD-Access decision, a WAN redesign where “what we did last time” is no longer an answer.
The course teaches design as a discipline: gathering requirements, scaling routing architectures, choosing between WAN options, planning for fabric and for failure. It prepares participants for exam 300-420, the design concentration of CCNP Enterprise — the standard credential for engineers whose output is architecture rather than configuration.
We organize delivery through authorized partners whose instructors design networks for real customers, not just for the courseware — live online in your time zone, on site, or as a private group built around the design decisions your team currently faces.
Who this course is for
- Senior engineers moving from implementation into design ownership
- Architects formalizing design practice for the CCNP Enterprise design concentration
- Presales and consulting engineers who defend designs in front of customers
- Team leads who review designs produced by integrators
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.
- Campus designs that survive growth, mergers and the next reorganization
- Routing design at scale: OSPF areas, EIGRP boundaries and BGP policy as architecture
- WAN and SD-WAN design decisions — and when the fashionable option is the wrong one
- Designing for SD-Access: fabric thinking and migration from the classic campus
- QoS, multicast and management treated as design inputs, not afterthoughts
- High availability as a property you design, not a feature you switch on

ENSLD 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 ENCOR (Enterprise Core)
The mandatory CCNP Enterprise core: implementation-focused, covering routing, switching, wireless and automation. ENCOR comes first for certification; ENSLD is the concentration for people whose deliverable is a design document rather than a configuration.
Cisco ENARSI (Advanced Routing)
The routing concentration: advanced configuration and troubleshooting, hands on the CLI. Choose ENARSI for engineers who operate and fix networks; ENSLD for those who decide what gets built. Both are 5-day professional-level courses.
A custom intensive
Facing one specific design decision — an SD-Access migration, a WAN redesign, a data-center-to-campus rethink? A custom 2–3 day design workshop on our materials works through your actual topology instead of the generic case studies.
Need only part of ENSLD?
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.

How does ENSLD fit into CCNP Enterprise?
ENSLD prepares you for exam 300-420, one of the concentration exams. Combined with the core exam covered by ENCOR, it completes CCNP Enterprise certification. It is the natural concentration for engineers moving toward architecture and design roles.
Is this a lecture course or hands-on?
Design courses work differently from implementation courses: instead of configuration labs, you work through design activities and case studies — requirements, constraints, trade-offs, and defending your choices. Participants say the arguing is the most useful part.
Does ENSLD cover wireless design?
Only at the architecture level — where the WLAN fits in the campus. Detailed wireless design, RF surveys and high-density planning are the subject of the dedicated ENWLSD course; teams owning both often plan them as a sequence.
Should we take ENCOR or ENSLD first?
For certification, ENCOR first: it covers the mandatory core exam and the implementation baseline that design discussion builds on. Experienced engineers who only need design skills, without the certification, sometimes take ENSLD standalone — that works too.
