This value of the object sdpBindSplitHorizonGrp specifies
the name of the split-horizon group where the spoke SDP
Bind belongs to. This object can be set only at the time
the row is created. Per default a spoke SDP Bind does not
belong to any split-horizon group. The name specified must
correspond to an existing split-horizon group in the TLS
service where this spoke SDP Bind is defined.
