This course is intended for network professionals, including designers, implementers, and support staff involved with design and deployment of large-scale networks for large enterprises or high-end ISP networks that use scalable technologies such as Intermediate System-to-Intermediate System (IS-IS), Open Shortest Path First (OSPF), Border Gateway Protocol (BGP), or Multiprotocol Label Switching (MPLS).

Upon completion of this course, you should be able to:

• Identify the critical factors for availability, scalability, and manageability
• Implement an Interior Gateway Protocol (IGP, either OSPF or IS-IS) into a large-scale hierarchical network using best current practices for scalability
• Implement BGP into a large-scale hierarchical network using best practices for scalability
• 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-autonomous-system environments
• Implement and verify MPLS traffic engineering practices
• Implement Layer 2 VPNs using Any Transport over MPLS (AToM)

Lab Outline

• Connect to the Lab Equipment

The purpose of this lab is to get you into the lab network so you can access reference materials used throughout the course and gain device access for later lab exercises.

• Configure the Basics

During the lab exercise you will configure the basic information needed to operate and manage the network equipment. You will import a configuration that installs a basic template, then configure many other elements manually.

• Configure Interfaces and IP Connectivity

The purpose of this lab exercise is to construct the lab and introduce you to the basic principles of constructing and configuring an IP network. In this lab you will configure the interfaces and establish IP connectivity.

• Configure and Verify OSPF or IS-IS in the Core Network

The purpose of this lab is to 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 IGP routing.

• Configure and Verify Basic Interior Border Gateway Protocol (IBGP)

The purpose of this lab exercise is to introduce you to BGP and full mesh IBGP routing within the lab network.

• Configure and Verify Exterior Border Gateway Protocol (EBGP)

During this lab exercise you will establish EBGP peering and verify route advertisement and reachability across the network.

• Scale BGP with Peer Templates and Route Reflectors

The purpose of this lab exercise is to configure route reflectors and observe the effect. You will also compare and contrast update groups to peer groups.

• Configure BGP Route Filtering

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

• 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 having connectivity 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.

• Configure and Verify MPLS

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

• Configure Intranet MPLS VPNs

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

• Configure Extranet MPLS VPNs

In this lab exercise you will simulate sharing VRF information with multiple sites. This could be a management LAN or a partner company.

• Configure and Verify MPLS Traffic Engineering (MPLS-TE)

In this lab exercise you will learn how to implement MPLS-TE tunnels.

• Implement, Verify, and Troubleshoot EoMPLS

This lab exercise demonstrates how to implement and verify EoMPLS functionality. You will implement a point-to-point emulated wire service (EWS) between customer edge routers using port mode Layer 2 transport.
