vRtrLdpAdjBackoffTable is a read-only table which augments the vRtrLdpHelloAdjTable. The purpose of this table is to keep backoff information about the LDP Hello Adjacencies on the virtual router. Use of AUGMENTS clause implies a one-to-one dependent relationship between the base table, vRtrLdpHelloAdjTable, and the augmenting table vRtrLdpAdjBackoffTable. This in effect extends the vRtrLdpHelloAdjTable with additional columns. Creation or deletion of a row in the vRtrLdpHelloAdjTable results in the same fate for the row in the vRtrLdpAdjBackoffTable.
