Description of the training: Cisco ENARSI Training Course – Enterprise Advanced Routing and Services
This 5-day course makes you autonomous in Cisco enterprise advanced routing and services: implementing, optimising and troubleshooting EIGRP, OSPF and BGP, route redistribution, MPLS L3 VPN, DMVPN, IPv6 and router security, and infrastructure-services troubleshooting. You deepen professional-level routing skills.
The course blends theory with guided hands-on labs. It follows the Cisco ENCOR course, which lays the core technologies.

Good to know
The course suits experienced networking profiles. A preliminary discussion validates your knowledge (routing, device management) and adjusts the pace across the five days. The ENCOR course is a recommended prerequisite.
Objectives of the training: Cisco ENARSI Training Course – Enterprise Advanced Routing and Services
By the end of the course, you will be able to:
- Install, configure, operate and troubleshoot enterprise networks;
- Implement and optimise EIGRP, OSPF and BGP;
- Master route redistribution and path control;
- Deploy MPLS L3 VPN, VRF-Lite and DMVPN;
- Secure IPv6 and Cisco routers;
- Troubleshoot infrastructure services (AAA, SNMP, NetFlow) and monitoring.
Prerequisites of the training: Cisco ENARSI Training Course – Enterprise Advanced Routing and Services
To follow this course under the best conditions, you should have a good understanding of networking fundamentals, LAN implementation, device management and security, and some automation notions. Having completed the ENCOR course is recommended.
Because every participant is unique, a personalised interview with our expert lets us design a course perfectly aligned with their objectives, level and professional challenges.

FAQ
What is ENARSI?
ENARSI (Implementing Cisco Enterprise Advanced Routing and Services) covers advanced Cisco enterprise routing and services skills: EIGRP, OSPF, BGP, redistribution, MPLS, VPNs and troubleshooting. This course covers its technical scope in an operational way.
How does it differ from ENCOR?
ENCOR covers enterprise network core technologies, whereas ENARSI specifically deepens advanced routing and services (MPLS, VPNs, troubleshooting). ENARSI targets experienced profiles and assumes ENCOR knowledge.
What is MPLS L3 VPN?
MPLS L3 VPN is a technology that lets a carrier or enterprise carry the traffic of several customers or sites in isolation over a shared infrastructure, using VRFs and label switching (MPLS). The course teaches its architecture and operation.
What is route redistribution?
Redistribution means exchanging routes between different routing protocols (for example from OSPF to EIGRP). It is essential in heterogeneous networks but tricky to master: the course covers its implementation and how to troubleshoot feedback loops.
What is DMVPN?
DMVPN (Dynamic Multipoint VPN) is a Cisco solution that dynamically establishes VPN tunnels between sites without manually configuring each link. It simplifies the secure interconnection of many remote sites. The course covers its implementation.
What is BGP and its attributes?
BGP (Border Gateway Protocol) is the routing protocol between autonomous systems. Its attributes (AS-Path, Local Preference, MED, etc.) allow fine-grained path selection. The course covers IBGP, BGP optimization and filtering.
