BCN - Building Core Networks with OSPF, IS-IS, BGP, and MPLS Boot Camp v6

Overview:

This 5-day course will teach you how to design, deploy, and maintain an Internet Service Provider (ISP) backbone, focusing on the operational design and scaling principles of routing protocols used in large-scale networks. This class will provide you with adequate hands-on practice with techniques used in implementing protocols such as OSPF, BGP, and MPLS in an ISP network.

Note: You are required to bring your own laptop and Ethernet cable to class.

Agenda:

Lab 1: Connect to the Lab Equipment

In this lab, you'll get into the lab network so you can access reference materials used throughout the course and gain device access for later lab exercises.

Lab 1-1: Configure the Basics

Configure the basic information needed to operate and manage the network equipment. You will configure everything that this course has covered so far. You will import a configuration that installs a basic template, then you will configure many other elements manually.

Lab 1-2: Configure Interfaces and IP Connectivity

In this lab, you will construct the lab and get an introduction to the basic principles of constructing and configuring an IP network. You will configure the interfaces and establish IP connectivity.

Lab 2-1 or Lab 2-2: Configure and Verify OSPF or IS-IS in the Core Network

Continue building the lab by configuring infrastructure routing using either OSPF or IS-IS. Using the basic router configuration from the first exercise, you will configure basic interior gateway protocol routing.

Lab 3-1: Configure and Verify Basic interior Border Gateway Protocol (IBGP)

Get an introduction to BGP and full mesh IBGP routing within the lab network.

Lab 3-2: Configure and Verify Exterior Border Gateway Protocol (EBGP)

Establish EBGP peering and verify route advertisement and reachability across the network.

Lab 4-1: Scale BGP with Peer Templates and Route Reflectors

In this lab exercise, you will configure route reflectors and observe the effect. You will also compare and contrast update groups and peer groups.

Lab 5-1: Configure BGP Route Filtering

Discover the types of routing policy available in BGP in this lab designed for you to practice filtering BGP updates using various filtering methods. The methods focus on prefix lists, community filters, and AS-path access lists.

Lab 5-2: Configure Multihoming Policy

This lab exercise demonstrates how an autonomous system can use local preference to control outbound traffic and use MEDs or metrics to control inbound traffic when multihoming or connecting to more than one other autonomous system. The goal of the exercise is to demonstrate how to achieve a particular traffic flow using different methods.

Lab 6-1: Configure and Verify MPLS

This lab exercise demonstrates how to implement and verify MPLS functionality into an existing network.

Lab 7-1: Configure Intranet MPLS VPN

In this lab exercise, you will learn how to implement MPLS VPNs into an existing network.

Lab 7-2: Configure Extranet MPLS VPNs

Simulate sharing VRF information with multiple sites such as a management LAN or a partner company.

Lab 8-1: Configure and Verify MPLS Traffic Engineering (TE)

Learn how to implement MPLS-TE tunnels in this lab exercise.

Lab 9-1: Implement, Verify, and Troubleshoot EoMPLS

In this lab, you will implement a point-to-point emulated wire service (EWS) between customer edge routers using port mode L2 transport.

Lab 10-1: Final Wrap-Up Lab

Audience:

• Individuals who deploy networks using OSPF, BGP, or MPLS technology in an enterprise or service provider environment

• Control routing policy by influencing the BGP path selection process using route maps, prefix lists, and community strings
• Implement multihoming strategies using multiexit discriminators (MEDs) and local preference
• Implement and verify MPLS functionality in a large-scale network
• Implement and verify MPLS VPN connectivity in intra-AS environments
• Implement and verify MPLS Traffic Engineering practices
• Characterize the features and requirements for implementation of Layer 2 VPNs (any Transport over MPLS)
