> having two NICs on the same subnet

I'm trying to wrap my brain around that in the larger network picture.  Two
NICs in the same subnet (presumably on the same computer) would have access
to the same other devices.  This could potentially increase bandwidth
(maybe?) and offer redundancy (if NICS, wiring or switches were the biggest
source of failure).  I'm not sure how the OS would decide which one to use
for a given packet, or if an application (such as Asterisk) could determine
which one to use.  I can see potential problems with addressing, as other
devices could send to one, and would definitely not know what to do with a
reply from the other, etc.  I'm not sure this would be an Asterisk bug.
Without some concept of what I am missing here, I would consider it a
cockpit error on system setup.  The only reason I can think of for having
two NICs in a computer would be using it as a router--in which case they
wouldn't be on the same subnet.  (OK I've done it before for redundant
paths, but again, the paths should be on different subnets, otherwise how
does one tell the OS which path was intended?)
