By default Solaris uses RIP. RIP uses a round robin algorithm to determine the default route if more than one is present. There has been a ton of questions about forcing it to use one or the other and you can setup a filter using ipf to accomplish that but Solaris has no mechanism to do what is called "Source Routing." Which is where the host determines the route to take to the endpoint.
Web Search Routing Information Protocol for more details.
But more pertinent to the original poster's question, while we don't support Source Routing,Is this documented anywhere? As in, it might turn into a blog post.
we do have support for the strong and src-priority hostmodel in Solaris 11. Strong hostmodel
will only send (locally originated) packets out to a default router on an interface that is on
the same subnet as the source address of the packet. The "src-preferred" hostmodel will
first try to the strong hostmodel behavior, and if no matching route can be found, will fall
back to the weak (default) hostmodel behavior.
