Configuring VPLS RSHG

To configure a group of SAPs in a VPLS service as a RSHG, add the residential-group parameter when creating the split horizon group. Traffic arriving on a SAP within an RSHG is not copied to other SAPs in the same split horizon group.

Note: The split horizon group must be created before it can be applied.

The following example displays a VPLS configuration with split horizon enabled:

*A:ALA-48>config>service>vpls# info
----------------------------------------------
            split-horizon-group "DSL-group2" residential-group create
                description "split horizon group for DSL - no broadcast supported"
            exit
            stp
                shutdown
            exit
            sap 2/1/4:100 split-horizon-group "DSL-group2" create
                description "SAP in RSHG"
            exit
            sap 2/1/4:200 split-horizon-group "DSL-group2" create
                description "another SAP in the RSHG"
            exit
            no shutdown
