A trace route hop entry.
The first index member specifies the hh3cFcTraceRouteEntry
that an hh3cFcTraceRouteHopsEntry is associated with. The
second index element identifies a hop in a trace route path.
In the case of a complete path being traced, entries
corresponding to an hh3cFcTraceRouteEntry are created
automatically in this table.
Each hop in the complete path will be listed in this table.
When an hh3cFcTraceRouteEntry is deleted or aged out, the
entries corresponding to the hh3cFcTraceRouteEntry in this
table are also deleted.
