CLI Guide

BGP graceful restart is active only when the neighbor becomes established. Otherwise it is disabled. Graceful-

restart applies to all neighbors with established adjacency.

bgp non-deterministic-med

Compare MEDs of paths from dierent 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 dierent ASs do not have their MEDs compared).

Command Modes ROUTER BGP

Supported Modes Full–Switch

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 dierent 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 the existing

paths remains Deterministic until you enter the clear ip bgp command to clear existing paths.

bgp recursive-bgp-next-hop

Enable next-hop resolution through other routes learned by BGP.
