According to Juniper, the MX uses separate memory for v4 and v6.
The numbers that I have seen for MX80 are:
v4 FIB 1mil
v4 RIB 4mil
v6 FIB 512k
v6 RIB 3mil
MX10 should be the same as it has the same RE, but just enables/licenses
different #s of ports. These are "conservative" numbers and I have seen
claims of higher actual capacity from some sources.
... I wouldn't expect that you would have any route memory issues moving
to dual stack ...
