Each row entry represents an instance of a service FEC sent to or received from an LDP peer. Use of AUGMENTS clause implies a one-to-one dependent relationship between the base table, vRtrLdpServFecTable, and the augmenting table, vRtrLdpCepTdmFecTable. This in effect extends the vRtrLdpServFecTable with additional columns. Creation or deletion of a row in the vRtrLdpServFecTable results in the same fate for the row in the VRtrLdpCepTdmFecEntry.
