Each row entry represents an association between a Labeled Switch
Path (P2MP LSP) in the vRtrMplsP2mpInstTable and a S2L sub LSP entry in
the vRtrMplsS2lSubLspTable. Entries in this table can be created and
deleted via SNMP SET operations. Setting RowStatus to 'active'
requires vRtrMplsS2lSubLspType to have been assigned a valid value.
