The correct sequence of BGP attributes for route selection is critical for determining how BGP routers make decisions about the best routes to use when multiple paths to a destination exist.

In this context, the order begins with local preference, which is significant because it is locally significant and indicates the preferred path for outbound traffic. BGP assigns the highest local preference to the routes that are most desirable within an autonomous system, thus influencing the route selection process.

Next in the sequence is the AS path attribute. This is a list of ASN (Autonomous System Numbers) that a route has traversed. It serves two primary purposes: it helps prevent routing loops and aids in the selection of the shortest path to the destination. When comparing routes, BGP favors the one with the shortest AS path.

The third in consideration is the origin attribute, which indicates the origin of the route. It allows BGP to ascertain how the route is advertised to the network—whether it originated from an Interior Gateway Protocol (IGP), a Border Gateway Protocol (EGP), or was redistributed.

Finally, the Multi-Exit Discriminator (MED) is used to influence the proper selection of routes when there are multiple paths into an AS from a neighboring AS. BGP favors the
