bgp log-neighbor-changes c e Enable logging of BGP neighbor resets. Syntax bgp log-neighbor-changes To disable logging, enter no bgp log-neighbor-changes. Defaults Enabled Command Modes ROUTER BGP Command History Version 8.4.2.1 Version 8.2.1.0 Version 7.4.1.0 Introduced on C-Series and S4810. Introduced on E-Series ExaScale Introduced on E-Series TeraScale Usage The bgp log-neighbor-changes command appears in the show config command output. Information Related Commands show config View the current configuration bgp non-deterministic-med c e Compare MEDs of paths from different Autonomous Systems. Syntax bgp non-deterministic-med To return to the default, enter no bgp non-deterministic-med. Defaults Disabled (that is, paths/routes for the same destination but from different ASs will not have their MEDs compared). Command Modes ROUTER BGP Command History Version 8.4.2.1 Version 8.2.1.0 Version 7.4.1.0 Introduced on C-Series and S4810. Introduced on E-Series ExaScale Introduced on E-Series TeraScale Usage 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.
