The easy way to do this would be to source the connection from a IP address bound to a VLAN on the interface you want the traffic to flow out. You can do this with the SNAT command.

snat  [] | none | automap

If the connection fails you can used the LD_FAILED event to reselect the link and source the connection from another IP address to use the other connection.
