COURSE OVERVIEW

Configuring BGP on Cisco Routers version 4.0 provides students with in-depth knowledge of Border Gateway Protocol (BGP), the routing protocol that is one of the foundations of the Internet and New World technologies such as Multiprotocol Label Switching (MPLS). This curriculum covers the theory of BGP, configuration of BGP on Cisco IOS routers, detailed troubleshooting information, and hands-on exercises that provide learners with the skills that they need to configure and troubleshoot BGP networks in customer environments. Different service solutions in the curriculum cover BGP network design issues and usage rules for various BGP features, preparing learners to design and implement efficient, optimal, and troublefree BGP networks.

AUDIENCE AND PREREQUISITES

This course is intended primarily for network administrators, network engineers, network managers and systems engineers who would like to implement BGP.
To participate in the hands-on labs in this class, you need to bring a laptop computer with the following:

Windows 7 or 8.1 or 10 is recommended. Mac OSX 10.6 or greater is supported as well.
1 GB or more of RAM
Browser Requirements: Internet Explorer 10 or greater or Mozilla Firefox. (Safari and Mozilla Firefox for Mac OSX)
All students are required to have administrator rights to their PCs and cannot be logged in to a domain using any Group Policies that will limit their machine’s capabilities.
If you do not have administrator rights to your PC, you at least need permissions to download, install, and run Cisco Any Connect Client.
If you are participating in a WebEx event, it is highly recommended to take this class at a location that has bandwidth speeds at a minimum of 1 Mbps bandwidth speeds
The knowledge and skills that a learner must have before attending this course are as follows: Intermediate to advanced knowledge of Cisco IOS Software configuration
Configuring and troubleshooting RIP, EIGRP, OSPF and IS-IS
Skills and knowledge equivalent to those learned in:
Interconnecting Cisco Networking Devices v2.0, Part 1 (ICND1 v2.0) and Part 2 (ICND2 v2.0), or Interconnecting Cisco Networking Devices: Accelerated Version 2.0 (CCNAX v2.0)
