next-hop-self
Disables the next-hop calculation for a neighbor.
Syntax
next-hop-self
Parameters None
Default Enabled
Command Mode ROUTER-NEIGHBOR-AF
Usage
Information
Influences next-hop processing of EBGP routes to IBGP peers. The no version of this command disables
the next-hop calculation.
Example
OS10(conf-router-neighbor-af)# next-hop-self
Supported
Releases
10.3.0E or later
non-deterministic-med
Compares paths in the order they arrive.
Syntax
non-deterministic-med
Parameters None
Default Disabled
Command Mode ROUTER-BGP
Usage
Information
Paths compare in the order they arrive. OS10 uses this method to choose different best paths from a set
of paths, depending on the order they are received from the neighbors. MED may or may not be
compared between adjacent paths. When you change the path selection from deterministic to
nondeterministic, the path selection for the existing paths remains deterministic until you use the clear
ip bgp command to clear the existing paths. The no version of this command configures BGP bestpath
selection as non-deterministic.
NOTE: To configure these settings for a nondefault VRF instance, you must first enter the ROUTER-
CONFIG-VRF sub mode using the following commands:
1. Enter the ROUTER BGP mode using the router bgp as-number command.
2. From the ROUTER BGP mode, enter the ROUTER BGP VRF mode using the vrf vrf-name
command.
Example
OS10(conf-router-bgp-10)# non-deterministic-med
Supported
Releases
10.2.0E or later
outbound-optimization
Enables outbound optimization for IBGP peer-group members.
Syntax
outbound-optimization
Parameters None
Default Not configured
Command Mode ROUTER-BGP
Usage
Information
Enable or disable outbound optimization dynamically to reset all neighbor sessions. When you enable
outbound optimization, all peers receive the same update packets. The next-hop address chosen as one
