compared).

Information
In non-deterministic mode, paths are compared in the order in which they arrive. This method can lead
to FTOS choosing different best paths from a set of paths, depending on the order in which they are
received from the neighbors since MED may or may not get compared between adjacent paths. In
deterministic mode (no bgp non-deterministic-med), FTOS compares MED between adjacent
paths within an AS group since all paths in the AS group are from the same AS.
When you change the path selection from deterministic to non-deterministic, the path selection for
existing paths remains deterministic until you enter capture bgp-pdu max-buffer-size command to clear
existing paths.
