Which of these BGP paths will be the preferred one ?

BGP path selection follows a specific order of attributes to determine the best path. The process prefers the path with the highest local preference first, as it is one of the earliest steps in the decision process. Local preference is used within an AS to influence outbound traffic. Only if local preferences are equal does it move to the next criteria, such as shortest AS path. The AS path length is considered after local preference, MED after that, and eBGP over iBGP even later. Therefore, among the options, the highest local preference (D) is the most preferred criterion. The original document's answer B is incorrect based on standard BGP selection rules implemented in Fortinet. Exact extract: This article describes the BGP route selection process. Scope FortiGate. Solution Consider only routes with no AS loops and a valid next hop. BGP makes routing decisions based on path, network policies and rulesets ... select the route with the lowest router ID as the best path. Network. Type. To achieve this, multiple route selection techniques can be used. Some are protocol-agnostic (for example, weight) and others are protocol-specific (for example ...).
