This object defines a single neighbor. There may
be several entries in this table for one neighbor,
defining different ways of reaching this neighbor.
Thus, there may be several entries in this table
with the same value of dialCtlNbrCfgId.
Multiple entries for one neighbor may be used to support
multilink as well as backup lines. A single neighbor
will be identified by a unique value of this object.
Several entries for one neighbor MUST have the same
value of dialCtlNbrCfgId and dialCtlNbrCfgIfIndex
but still different ifEntries and thus different
values of dialCtlNbrCfgIndex.
