Subject: Re: multipath routing
Multipath takes a little more that just setting the default
route. You
have to set separate routing tables for each interface involved in
the
multipath routing (though I haven't understood yet why they
are
needed.. the fact is that if you don't set them, multipath
won't
route).
Also, even if you set it all right, it doesn't mean that
if you send
two packets to a location X, one will go through one interface
and the
second will go through the other. Routes are cached, and after
a
routing decision has been made for the first packet, packets going
to
that same host will go through the same interface till the caching
time
has gone by.
