BGP - What is the Originate Attribute?

The BGP originate attribute is used by the protocol's best path algorithm to compare locally originated routes with those learned from BGP peers. A BGP router will prefer the path that was originated by the local BGP router over routes learned from BGP peers. In this video, I'll be explaining how this attribute is used, and how it can affect the decisions made by BGP when choosing the best path. Note, the Originate attribute should not be confused with the Origin attribute which is a separate attribute examined further down the algorithm process. 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...)
