The Local Preference or (LOCAL_PREF) attribute is the first BGP attribute that is examined in the BGP best path algorithm, according to the official definition of the protocol. But what is this attribute and why is it important? In this video, I'll be examining how LOCAL_PREF is used and why it is important in choosing the best path.

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...)
