Usage
Information
In Non-Deterministic mode, paths are compared in the order in which they arrive.
This method can lead the system to choose different best paths from a set of
paths, depending on the order in which they are received from the neighbors
because MED may or may not get compared between adjacent paths. In
Deterministic mode (no bgp non-deterministic-med), the system compares
MED between adjacent paths within an AS group because 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 the existing paths remains Deterministic until you enter the
clear ip bgp command to clear existing paths.
