Well, IMHO, the way I've done Junos-based route reflectors 
that are neither in the forwarding path nor running MPLS is 
to import the necessary RIB's accordingly, negating the need 
for the 0/0 static route approach:

routing-options {
    rib-groups {
        IGP-RIB {
            import-rib [ inet.0 inet.3 inet6.3 ];
        }
    }
}

This way, you don't need to run MPLS on any of the route 
reflector's interfaces.

If you're willing to, perhaps try that and see if it helps.
