BGP Path Attributes
BGP uses BGP Path Attributes to determine the Best Path to a destination. According to BGP Best Path Algorithm, BGP Path Attributes are used to determine the BGP Best Path selection.
With these Path Attributes, network administrators can manage the BGP Traffic and determine way of the BGP traffic flow.
