It's a J-series, not MX, but should be the same:

forwarding-options {
     helpers {
         bootp {
             interface {
                 ge-0/0/2.2021 {
                     server x.x.x.x routing-instance BLAH;

...and


routing-instances {
     BLAH {
         instance-type vrf;
         interface ge-0/0/2.2021;

Basically, you have to put the routing-instance on the server option, 
matching the routing instance of the interface.
