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 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 clear ip bgp command to clear existing paths. Command History Version 8.3.5.0 Version 7.8.1.0 Version 7.7.1.0 Introduced on the S55. Introduced support on S-Series Introduced support on C-Series bgp recursive-bgp-next-hop c e s Enable next-hop resolution through other routes learned by BGP. Syntax bgp recursive-bgp-next-hop To disable next-hop resolution, use the no bgp recursive-bgp-next-hop command. Defaults Enabled Command Modes ROUTER BGP Usage Information This command is a knob to disable BGP next-hop resolution via BGP learned routes. During the next-hop resolution, only the first route that the next-hop resolves through is verified for the route's protocol source and is checked if the route is learned from BGP or not. The clear ip bgp command is required for this command to take effect and to keep the BGP database consistent. Execute the clear ip bgp command right after executing this command.
