ENARSI Training for Your Team — Implementing Cisco Enterprise Advanced Routing and Services
Enterprise WANs accumulate routing debt quietly: redistribution added during a migration, BGP policy written by an engineer who left, a DMVPN overlay that “mostly works”. Everything holds — until a link flaps and traffic takes a path nobody designed. ENARSI (Implementing Cisco Enterprise Advanced Routing and Services) is the course for engineers who have to make that stack predictable rather than merely alive.
The course builds two capabilities that rarely come together: advanced configuration of OSPF, EIGRP, BGP, redistribution and VPN services, and a structured troubleshooting method for finding out why they misbehave. It prepares participants for exam 300-410, a CCNP Enterprise concentration — the classic pairing with ENCOR for engineers whose specialty is routing itself.
As a training operator, we organize ENARSI delivery through authorized partners with instructors who troubleshoot enterprise routing for a living — live online in your time zone, at your site, or as a private group weighted toward the protocols your WAN actually runs.
Who this course is for
- Network engineers who own routing across complex enterprise WANs
- CCNP Enterprise candidates taking the classic routing concentration after ENCOR
- Escalation and NOC engineers who inherit routing incidents nobody can explain
- Integrator engineers formalizing routing depth for partner requirements
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.
- OSPF and EIGRP at scale — the corner cases that only appear in real topologies
- BGP path control for multihomed enterprise edges that behaves as designed
- Route redistribution without loops, and finding the loops you inherited
- VPN services across the WAN: DMVPN and MPLS-based connectivity
- Hardening the routing layer without breaking the routing
- Structured troubleshooting method — evidence first, reboot last

ENARSI 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 CCNP Enterprise core: a broad curriculum across routing, switching, wireless and automation. Take ENCOR first — it covers the mandatory core exam; ENARSI is the deep-dive concentration for engineers who then specialize in routing and services.
Cisco ENSDWI (SD-WAN)
The SD-WAN concentration: controller-managed WAN instead of hand-built routing. Choose ENSDWI if your WAN roadmap is Catalyst SD-WAN; choose ENARSI if you run BGP, OSPF and DMVPN directly and need to troubleshoot them under pressure.
A custom intensive
If your team needs only the BGP and redistribution material applied to your own topology, a custom 2–3 day program on our materials covers exactly that scope — with your configurations on the bench instead of generic labs.
Need only part of ENARSI?
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.

Is ENARSI enough for CCNP Enterprise certification?
ENARSI prepares you for exam 300-410, one of the concentration exams. CCNP Enterprise also requires the core exam covered by the ENCOR course. Most teams take ENCOR first and choose ENARSI as the concentration when advanced routing is their day job.
How much of the course is troubleshooting?
A large share. ENARSI pairs advanced configuration with structured troubleshooting of routing protocols, redistribution and VPN services. Labs deliberately include broken scenarios, because diagnosing a topology you did not build is the skill both the exam and production actually test.
Does ENARSI cover SD-WAN?
Only at the edges. ENARSI is about classic advanced routing — OSPF, EIGRP, BGP, redistribution, DMVPN and MPLS-based services. For Catalyst SD-WAN design and operation, the ENSDWI course is the right track; we can plan both as a sequence.
What should participants know before the course?
Solid CCNA-level networking plus working exposure to OSPF, EIGRP and BGP in production. Engineers fresh from CCNA usually benefit from ENCOR first; for a mixed group we can assess levels and split delivery across the two courses.
