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
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 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 outbound-optimization
Enables outbound optimization for IBGP peer-group members.
Syntax
bgp outbound-optimization
To disable outbound optimization, enter the no bgp outbound-optimization command.
Defaults Enabled.
Command Modes ROUTER BGP
