As we continue to move down the list of BGP attributes that are examined to determine the best path, one of the last attributes to be examined is the router ID. BGP prefers the route that is learned from the neighbor with the lowest router ID. In this video, I'll be explaining this particular attribute, and we'll see how it is used to break the tie.

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...)
