Applied Materials IT Network Engineer Interview Questions and Answers

BGP path selection process determines the best path for routing traffic between autonomous systems.

• BGP prefers the path with the highest weight attribute.

• If weights are the same, BGP looks at the local preference attribute.

• Next, BGP considers the AS path length.

• BGP then looks at the origin code, preferring IGP over EGP and Incomplete.

• If all else is equal, BGP chooses the path with the lowest router ID.
