Joel,

So far, I did not answer the last question of your initial email.
Please find an answer inline.

It is a common option of existing traceroute implementations.
For the BSD traceroute it reflects the -r option:

     -r      Bypass the normal routing tables and send directly to a host on
             an attached network.  If the host is not on a directly-attached
             network, an error is returned.  This option can be used to ping a
             local host through an interface that has no route through it
             (e.g., after the interface was dropped by routed(8)).

Object traceRouteCtlByPassRouteTable gives access to this option.
I agree that it is not really needed if also the PING MIB is available.
It might be useful, however, if not.  Anyway, it is contained in the first
version of the TRACEROUTE MIB in RFC 2925 and it would create an unnecessary
incompatibility if we removed it.

Thanks,

    Juergen
