Not quite - you can't define the same interface twice in two different instances, so you use rib-groups to import interface routes into the forwarding-instance.  

You configure any static routes etc. under the forwarding-instance in the normal way.

There is a guide below for the SRX which should give you a good start:

Just ignore the security bits for M/MX.
