Course Description

The Cisco CCNA exam now requires that you know BGP. This is the exam topic Cisco have listed for the exam: "Configure and verify single-homed branch connectivity using eBGP IPv4 (limited to peering and route advertisement using Network command only)"

In this course you will learn the basics of BGP as well as investigate multiple troubleshooting scenarios to help you prepare for the exam.

Border Gateway Protocol (BGP) is an exterior gateway protocol designed to exchange routing and reachability information among autonomous systems (AS) on the Internet. The protocol is often classified as a path vector protocol but is sometimes also classed as a distance-vector routing protocol. The Border Gateway Protocol makes routing decisions based on paths, network policies, or rule-sets configured by a network administrator and is involved in making core routing decisions.

BGP may be used for routing within an autonomous system. In this application it is referred to as Interior Border Gateway Protocol, Internal BGP, or iBGP. In contrast, the Internet application of the protocol may be referred to as Exterior Border Gateway Protocol, External BGP, or eBGP.

BGP4 is standard for Internet routing, required of most Internet service providers (ISPs) to establish routing between one another. Very large private IP networks use BGP internally. An example is the joining of a number of large Open Shortest Path First (OSPF) networks, when OSPF by itself does not scale to the size required. Another reason to use BGP is multihoming a network for better redundancy, either to multiple access points of a single ISP or to multiple ISPs.

this was put in amazing order to follow along. I feel like I learned more from this video than from a CCNA book when it comes to comprehension. I love the order! Thank you!

Slow pace teaching. Straight to the point. All verification (Show) command are mentioned with explained purpose on why it was used. Thank you so much Sir David Bombal.

Very Well.. Executed Troubleshoot. Many People get stuck with the basic faults itself. Its important for learners to pick the point with this series. Thanks David!

I was scared about the whole BGP thing...but he he really simplified the topic for me. I believe with more real world troubleshooting problems the course could be awesome!

By Gerardo Torres on 4/10/2018

Specific questions get proper answer in a matter of minutes. Learning by troubleshooting is excellent for common lab mistakes and also real-life situations that may occur. Thanks.

By Abhinav Kumar on 1/16/2018

I think this course gave me good insight about Border Gateway Protocol and basic configuration and troubleshooting parts was good to understand. But a more real world practical scenario based explanation would have been engaging.

By Ranjana V on 10/17/2017

Basic bringup and familarising with troubleshooting connectivity issues . This will help for engineers who has not much knowledge about functioning of bgp

By Matthew Wood on 9/6/2017

quality meat and potatoes, great simple lab you can easily spin up in GNS3 quickly to get used to the commands and see how BGP works. best beginning example I have seen, usually the teacher wants to add lots of stuff to the topology, this is not needed when you are just trying to see how BGP works at first and get used to the show commands and advertisements, as well as reading the output from BGP.

Every Teacher or Instructor needs to emulate David's style of teaching. This is what I've been looking for. I do hope he continues to put more courses on udemy.
