One of the things that is checked by the BGP best path algorithm is whether a particular route was learned via eBGP or iBGP. If all previous attributes are equal, this characteristic is used as a tie breaker. eBGP routes are chosen over iBGP routes. In this video, I'll show you how this attribute operates, and I'll also explain why this is the case.
Border Gateway Protocol, or BGP, is a routing protocol that uses a series of attributes to determine the best path through large networks such as the Internet. These attributes are examined in a standardized and predefined sequential order.
If you want to find out more about the BGP routing protocol, or the method by which attributes are used to determine the best path, take a look at some of my other videos linked below (after the chapter list...)
