Course overview

This course provides students with the essential BGP knowledge required to take full advantage of the Nokia Services Architecture course, specifically in topics related to layer-3 VPN services. This course also describes how MPLS tunnels can be stitched together by having BGP advertise labels in addition to IP prefixes. This course starts with basic concepts that include BGP messages, peering sessions, path attributes carried by route updates, as well as the list of criteria used by BGP to select the “best” route when the same prefix is being advertised by two or more routers. The course also describes different address families supported by BGP in addition to the traditional IPv4 prefixes. The course concludes with a module that explains route reflectors as a means to improve BGP scalability within an autonomous system. All use cases and lab exercises are based on the model-driven command-line interface (MD-CLI).

Course objectives

After completing the course, students should be able to:

  • Describe the role of BGP
  • Describe how a BGP-capable router selects the best path if it receives more than one update describing the same address
  • Explain how route policies can be used to modify the default behavior of a BGP speaker
  • Explain that BGP was originally designed to exchange IPv4 prefixes only, but it was later extended to exchange other types of addresses as well
  • List some of the most important address families supported by BGP, including IPv4, IPv6, VPN-IPv4, VPN-IPv6, Label-IPv4 and Label-IPv6
  • Explain that iBGP peers typically require a full mesh of iBGP sessions, which is not a scalable approach
  • Describe the concept of route reflector and explain how it improves scalability by relaxing the full-mesh requirement

Prerequisites

Nokia IS-IS Routing Protocol or Nokia OSPF Routing Protocol course

Having completed the Nokia Multiprotocol Label Switching course would be beneficial for some topics.
