Configuring a VPLS Service with CLI
Configuring VPLS SAPs with Split Horizon
To configure a VPLS service with a split horizon group, add the split-horizon-group parameter
when creating the SAP. Traffic arriving on a SAP within a split horizon group will not be copied
to other SAPs in the same split horizon group.
Example
config>service>vpls# sap 1/1/3:100 split-horizon-group DSL-group1
create
config>service>vpls>sap$ no shutdown
config>service>vpls>sap# description "SAP for residential bridging"
config>service>vpls>sap# exit
config>service>vpls# sap 1/1/3:200 split-horizon-group DSL-group1
create
config>service>vpls>sap$ no shutdown
config>service>vpls>sap# description "SAP for residential bridging"
config>service>vpls>sap# exit
config>service>vpls#split-horizon-group DSL-group1
config>service>vpls>split-horizon-group#description "Split horizon
group for DSL"
config>service>vpls>split-horizon-group#exit
The following example displays the VPLS configuration with split horizon enabled:
