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 a SAP or spoke SDP within a split horizon group will
not be copied to other SAPs or spoke SDPs in the same split horizon group.
The following example displays a VPLS configuration with split horizon enabled:
