Cisco BGP and MPLS

Border Gateway Protocol (BGP) is the routing technology that enables the largest and most sophisticated network in the world today – the Internet.

BGP is also one of the critical underlying foundations of new-world technologies such as Multiprotocol Label Switching (MPLS).

MPLS VPN is one the most common technology used by service provider

This course covers MPLS concepts with practical scenarios in detail.

The course focuses on VPN technology issues of MPLS from the Service Providers perspective and how to configure some of those features and functions in an existing routed environment.

Target Audience

  • Everyone interested in running BGP and MPLS.
  • Technical engineers and delegates seeking Cisco certifications including CCNP RS or CCNA/CCNP Service provider or Cisco Certified Internetwork Expert (CCIE Routing & Switching) or CCIE Service Provider
  • This course is recommended for any student interested in mastering advanced Internet and related Cisco technologies

Prerequisites

  • Students enrolled in this course should possess a strong knowledge of networking a Transmission Control Protocol/Internet Protocol (TCP/IP) and have completed the Network Associate level certification or have the equivalent knowledge and experience.
  • Good Foundation on CCNA RS, CCNP RS Concepts

Course Objectives

  • The Course Goal is to provide learners with in-depth knowledge of BGP
  • Configure, monitor, and troubleshoot basic BGP to enable inter-domain routing in a network scenario with multiple domains
  • Use BGP policy controls to influence the route selection process
  • Use BGP attributes to influence the route selection process
  • Implement the correct BGP configuration to successfully connect the customer network to the Internet in a network scenario where you must support multiple connections
  • Identify common BGP scaling issues and enable route reflection and confederations as possible solutions to these issues in a typical service provider network with multiple BGP connections to other autonomous systems
  • Use available BGP tools and features to optimize the scalability of the BGP routing protocol in a typical BGP network
  • Design, Implement & Verify MPLS L3 VPN
  • Supporting multiple Customer sites
  • Monitor & troubleshoot MPLS L3 VPN
  • Features and functions such as Traffic Engineering, Layer 2VPN.
