I do not know what your setup and exact needs are, but have you
tried the "src" option of the "ip route" command?

Example:

ip route add dev eth1 192.168.1.0/24 src 10.0.1.1
                                     ^^^^^^^^^^^^

The routing code uses the primary IP address of the outgoing
interface, unless you explicitly configure the preferred
source address (as in the example above).
