Howdy,
  If you want to really understand this, you will need to read up on
TCPIP.  I am not an expert, but I understand it well enough to use it. 
Having written that, I will probably make some embarrassing mistake, but
I'll go on anyway.  I can't give you a paragraph description(at least
not tonight, because I need to get to sleep).  Maybe someone else on the
list can.  The tcpip stack uses a combination of factors to decide how
to route a packet.  The IP address and netmask for each interface are
important factors.  That's why you define the gigabit nics on their own
private IP range with a netmask like 255.255.255.252.  The result is
that the 4 ip addresses that survive that netmask should always go
through that interface.  That is to say, on machine A with an IP of
10.0.1.1 and a netmask of 255.255.255.252, an ip request for 10.0.1.0,
10.0.1.2, or 10.0.1.3 should always use that interface.
Good night,
Ralph
