CLI Guide

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 does
not have their MEDs compared).
Command Modes ROUTER BGP
Supported Modes Full–Switch
Command History
Version Description
9.9(0.0) Introduced on the FN IOM.
9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
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
mode, the path selection for existing paths remains Deterministic until you enter
the capture bgp-pdu max-buffer-size command to clear existing paths.
bgp recursive-bgp-next-hop
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
Supported Modes Full–Switch
Command History
Version Description
9.9(0.0) Introduced on the FN IOM.
9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information
This command is a knob to disable BGP next-hop resolution using 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.
