Geof, the Berkeley/UNIX "routed" router (and other similar routing protocols)
choose among equal-cost routes semi-randomly.  Different hosts and gateways
may then choose different gateways for the same destination.  The same
is true for hosts that use one of several default gateways and then process
redirects from them; they'll either choose a suitable gateway, or be
redirected to that particular gateway's choice of next-hop router.
None of this manages carefully-equalized load balancing, but does tend
to spread out the load among multiple gateways.
