Service Manual

BGP graceful restart is active only when the neighbor becomes established.
Otherwise it is disabled. Graceful-restart applies to all neighbors with established
adjacency.
This command automatically restarts the BGP instance for the configuration to
take effect.
bgp non-deterministic-med
Compare MEDs of paths from different autonomous systems.
Syntax
bgp non-deterministic-med
To return to the default, use the no bgp non-deterministic-med command.
Defaults Disabled (that is, paths/routes for the same destination but from different ASs do
not have their MEDs compared).
Command Modes ROUTER BGP

Usage Information
In Non-Deterministic mode, paths are compared in the order in which they arrive.
This method can lead to Dell Networking OS 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), Dell Networking OS
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.
