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

Once engineers are comfortable with the core of enterprise networking, the next challenge is depth. They are expected to connect new regional offices, integrate networks after a merger, link to more than one provider, and keep everything stable while the network keeps growing. Implementing Cisco Enterprise Advanced Routing and Services (300-410 ENARSI) is designed to build exactly that depth.

The course continues where ENCOR leaves off. Topics that ENCOR introduces, such as OSPF, BGP and policy-based routing, are explored in much greater detail here, and new areas such as EIGRP troubleshooting, mutual redistribution, DMVPN and MPLS VPNs are added.

On the routing side, you will work through EIGRP successors and feasible successors, stub routers, metrics and load balancing. You will then troubleshoot OSPFv2 and OSPFv3 neighbour issues, authentication, network types, special areas such as stub and NSSA, and virtual links. BGP coverage includes neighbour relationships, attributes, best-path selection, route reflectors and filtering policies, for both IPv4 and IPv6.

The course places strong emphasis on how routing information is controlled. Administrative distance, route maps, tagging, summarisation and redistribution are taught together, so you understand how one change can affect the whole network. Policy-based routing and VRF-Lite add further control.

Two further areas complete the programme. VPN technologies cover single-hub DMVPN with NHRP and IPsec, along with MPLS and Layer 3 VPN concepts. Infrastructure security and services cover AAA, ACLs, uRPF, CoPP, IPv6 first-hop security, SNMP, logging, DHCP, IP SLA, NetFlow, and Cisco Catalyst Center Assurance.

For engineers ready to take the next step, this Cisco ENARSI training offers a structured, troubleshooting-focused path aligned with the 300-410 exam.

Course Objectives

Through this course, learners will:

• Gain expert-level troubleshooting skills for EIGRP, including neighbour relationships, loop-free path selection, stubs, metrics, and load balancing.
• Develop a thorough understanding of OSPFv2 and OSPFv3 network types, area types, router roles, virtual links and path preference.
• Learn to configure and troubleshoot BGP for internal and external peers, including attributes, route reflectors and inbound and outbound policies.
• Build safe redistribution designs using route maps, tagging, filtering, and summarisation to prevent loops and suboptimal routing.
• Apply policy-based routing and VRF-Lite, and understand how BFD supports faster convergence.
• Implement single-hub DMVPN and understand MPLS label switching and Layer 3 VPN architecture.
• Secure and support the infrastructure with AAA, ACLs, uRPF, CoPP, DHCP, SNMP, IP SLA, and NetFlow.
