Usage
Information
In non-deterministic mode, paths are compared in the order in which they arrive.
This method can lead to the system choosing 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 existing paths remains deterministic until you enter the
clear
ip bgp
command to clear existing paths.
