Implementing Cisco Enterprise Advanced Routing and Services (300-410 ENARSI)

As organisations connect more branches, regional offices, data centers, and service providers, routing becomes one of the most critical parts of the network. Banks, mobile operators, ports, utilities and government agencies all need engineers who can keep traffic flowing along the right path and fix problems before users notice. Our Cisco ENARSI course, Implementing Cisco Enterprise Advanced Routing and Services (300-410 ENARSI), is designed for network professionals who want to take their routing skills to an advanced, professional level.

Layer 3 technologies make up 35% of the 300-410 ENARSI exam, and this advanced routing training treats them in depth. You will troubleshoot EIGRP in classic and named mode, including feasible successors, stub routing, and unequal-cost load balancing. You will analyse OSPFv2 and OSPFv3 network types, special areas such as stub and NSSA, ABR and ASBR behaviour, and virtual links. BGP coverage includes iBGP and eBGP neighbour relationships, authentication, path attributes, best-path selection, route reflectors and inbound and outbound policies for both IPv4 and IPv6.

Just as important is learning how routing information is controlled. The course explains how administrative distance, route maps, route tagging, summarisation and mutual redistribution affect the routing table, and how to prevent the loops and suboptimal paths that redistribution can cause. Policy-based routing, BFD and VRF-Lite give engineers finer control over path selection, convergence and traffic separation, skills that are essential in multi-site and multi-provider networks.

Beyond routing, the 300-410 ENARSI training covers VPN technologies, infrastructure security and infrastructure services. You will configure single-hub DMVPN with GRE/mGRE, NHRP and IPsec, including spoke-to-spoke tunnels, and learn how MPLS and MPLS Layer 3 VPNs operate in provider networks. Security topics include AAA with TACACS+ and RADIUS, IPv4 ACLs, IPv6 traffic filters, uRPF, Control Plane Policing and IPv6 first-hop security. Infrastructure services cover secure device management, SNMPv3, syslog and conditional debugs, DHCP and DHCPv6, IP SLA, NetFlow and Cisco Catalyst Center Assurance.

Aligned with the current 300-410 ENARSI v1.1 exam, this Cisco ENARSI training prepares engineers for the exam that earns the Cisco Certified Specialist – Enterprise Advanced Infrastructure Implementation. Combined with the 350-401 ENCOR core exam, ENARSI completes the CCNP Enterprise certification, making this CCNP Enterprise course the natural next step for ENCOR-trained network engineers who want deeper troubleshooting expertise.

Course Objectives

On completing this Cisco ENARSI training, learners will be able to:

• Interpret and correct routing behaviour using administrative distance, route maps, tagging, filtering and summarisation.
• Troubleshoot EIGRP for IPv4 and IPv6, including loop-free path selection, stub routing and load balancing.
• Troubleshoot OSPFv2 and OSPFv3 adjacencies, network types, special areas, router types and virtual links.
• Construct and troubleshoot BGP peerings, attribute-based path selection, route reflectors and routing policies.
• Design safe redistribution and apply policy-based routing and VRF-Lite to control and segment traffic.
• Deploy single-hub DMVPN with NHRP and IPsec, and describe MPLS and MPLS Layer 3 VPN operation.
• Secure and maintain the infrastructure using AAA, ACLs, uRPF, CoPP, SNMP, logging, DHCP, IP SLA, and NetFlow.
