   of AFI and SAFI qualifiers, the logical addressing of a row in the
   bgp4PathAttrClusterTable (for example) would extend out some 50 bytes
   if there was no direct index linkage to the "governing" bgp4PathAt-
   trTable, and bgpPeerTable entries.

   For this reason, the tables are structured in such a way that, where
   there is such a linkage to a "dependent" table (where, for example,
   the bgpPrefixCountersTable "depends on" the bgpPeerTable), a table
   will contain a per-row numeric index (e.g., bgpPeerIndex), which the
   "dependent" table will use as one of its own row index values.  These
   indices are manufactured by the agent, and are otherwise opaque to
   the management application (or, for that matter, even to the
