This is how I understood it (and I would greatly appreciate any
correction on this):
. if you specify two routes with an equal metric value (using the
"metric" or "preference" keyword), load balancing is done on a per
connection basis;
. if you specify the "equalize" keyword on two routes (which of course
must have the usual triplet matching) then load balancing is done on a
packet basis;
. I tried to analyze the code (net/ipv4/fib_semantics.c) but I
couldn't understand where the "weight" parameter came from, given also
that the "weight" keyword in the ip user level command refers to
multicast routes.
