There can only be 1 path to a destination at 1 time.

This being said you can use dynamic routing to distribute the load
across 2 paths with 'gated' by putting 2 default routes with equal
weight in the gated.conf and then gated will be responsible for
adding and removing the default route from the system's routing
table on a per-packet or per-connection basis.

You will need to select a routing protocol and have a peer that
can reciprocate this routing information.
