Configuring VPLS spoke SDPs with split horizon

To configure spoke SDPs with a split horizon group, add the split-horizon-group parameter when creating the spoke SDP. Traffic arriving on an SAP or spoke-SDP within a split horizon group is not copied to other SAPs or spoke SDPs in the same split horizon group.

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