Cisco Advanced Routing: Tier 3 Service Providers
Service Provider networks are great places to expand your networking skills and perspectives. This course will teach you how to configure and troubleshoot routing protocols and IP services using a large-scale network topology.
What you'll learn
Believe it or not, enterprise and service provider networking technologies are converging, and this course helps illustrate that. In this course, Cisco Advanced Routing: Tier 3 Service Providers, you’ll learn to design, configure, and manage a small Internet Service Provider (ISP), which in many ways resembles a large enterprise. First, you’ll explore OSPF, a complex and popular routing protocol common deployed in enterprises and service providers alike. Next, you’ll apply BGP both for upstream Internet connectivity and MPLS layer-3 VPN service, which large enterprises commonly use to provide multi-tenancy at scale. Finally, you’ll learn how to optimize the network using a subset of common IP services relating to management, monitoring, and security. Most of these topics are discussed using both IPv4 and IPv6 in the context of dual-stacking. When you’re finished with this course, you’ll have the skills and knowledge of Cisco enterprise networking needed to manage large sized enterprise networks.

Course FAQ
In this course, you will learn how to utilize a novel 20-node topology to demonstrate multi-area OSPF with route filtering and summarization, complex route redistribution, MPLS Layer 3 VPN with BGP route reflection and more.
An area border router is in the ISPF boundary between two areas.
The OSPF (Open Shortest Path First) protocol is one of a family of IP routing protocols, and is in Interior Gateway Protocol for the internet. OSPF is used to distribute IP routing information throughout a single Autonomous System in an IP network.
Prerequisites for this course include: The Cisco Enterprise Core learning path, which is available here on Pluralsight.
This course is for IT professionals who are looking to create and manage their own Cisco enterprise network.
