Implementing Cisco Enterprise Advanced Routing and Services (ENARSI)

In this Implementing Cisco Enterprise Advanced Routing and Services course provides in-depth coverage of advanced enterprise routing technologies, services, and troubleshooting methodologies used in modern Cisco networks. It is designed for experienced network engineers who need to design, optimize, and troubleshoot complex routed environments across enterprise and service-provider-style architectures. The curriculum emphasizes protocol behavior, route control, and real-world operational problem solving.

Students gain deep technical expertise in dynamic routing protocols, including EIGRP, OSPF, and BGP, with extensive focus on optimization, authentication, path selection, and troubleshooting. Advanced topics such as route redistribution, policy-based routing, MP-BGP, VRF-Lite, MPLS L3 VPN concepts, and DMVPN are explored to demonstrate scalable routing design and segmentation. IPv4 and IPv6 services, including DHCP and first-hop security, are integrated throughout the course to reflect modern dual-stack network requirements.

The course also addresses infrastructure security, network services, and operational visibility, including access control, uRPF, and network management troubleshooting. Cisco DNA Center Assurance is introduced as a tool for proactive monitoring and issue resolution. Extensive hands-on labs reinforce theoretical concepts, enabling students to configure, verify, optimize, and troubleshoot routing protocols and services in realistic enterprise scenarios, preparing them for advanced roles and the 300-410 certification exam.
