Ok... let me put it this way.  If I'm on a Cisco router I have to issue a 
specific command to turn on IP routing.  If I'm on a NT box I have to launch 
a specific service to turn on IP routing.  What I'm hearing you say is that 
running a routing daemon is NOT the specific mechanism that turns on IP 
routing on a Sol8 box?  That's fine, but then what IS the procedure for 
turning IP routing on or off?

Understood.

Yes, those were my opinions as well.

Hmm.  It does have those exact three, as I mentioned, but they don't seem to 
be sufficient.  The only one I am adding via the gateways file is the 
default; the others are being added automagically, I assume as part of the 
normal initialization of the interfaces.

Yes.
