BGP Path Selection Process

Overview/Description
To configure BGP to manipulate the path selection process to routing operation and bandwidth utilization

Target Audience
Network engineers responsible for configuring, implementing, troubleshooting, and managing medium-to-large routed networks in an enterprise or service provider environment; network architects responsible for designing networks that support multiple routing protocol types; CCNP, CCDP, and CCIP candidates; CCIE routing and switching candidates

Prerequisites
A good understanding of networking terms, topologies, and the OSI reference model; familiarity with TCP/IP and configuring IP address schemes, including subnetting and variable-length subnet masking (VLSM); experience of operating and configuring Cisco routers for general use and configuring basic routing protocol implementations

Expected Duration
140 Minutes

Objectives:

BGP Path Selection Process

  • explain how BGP Version 4 is related to CIDR and how it implements route summarization.
  • identify the various BGP attributes and their characteristics and determine how they are evaluated to select optimal paths.
  • optimize BGP using route aggregation and monitor the BGP path selection process.
  • configure route maps to set local preference.
  • configure route maps to set multi-exit discriminator.
  • select the best implementation for multihoming autonomous systems given the benefits and drawbacks of mulithoming design options.
  • configure a BGP route map to change MED and local preference values.
