Command:

ipx eigrp-sap-split-horizon


Mode:

Router(config)#


Syntax:

 

ipx eigrp-sap-split-horizon

no ipx eigrp-sap-split-horizon


Syntax Description:

 

This command has no arguments or keywords.


Command Description:

To configure EIGRP SAP split horizon, use the ipx eigrp-sap-split-horizon global configuration command. To revert to default, use the no form of this command.

When split horizon is enabled, EIGRP SAP update and packets are not sent back to the receiving interface. This reduces the number of EIGRP packets on the network. Split horizon blocks the advertising of information from SAPs to the source router. This behavior optimizes communication among multiple routers. However, with nonbroadcast networks, such as Frame Relay and SMDS, situations can arise for which this behavior is less than ideal. For these situations, you may wish to disable split horizon.


Example:

The following example disables split horizon on the router:

Router(config)#no ipx eigrp-sap-split-horizon


Misconceptions:

 

When the ipx sap-incremental split-horizon interface configuration command is configured, it takes precedence over the ipx eigrp-sap-split-horizon command.
