Engineering team for QFX5100 BU (same Tridend2 box as ACX5048) released a new version with ECMP for MPLS:
See the release notes bellow: http://www.juniper.net/techpubs/en_US/junos14.1/information-products/topic-collections/ex-qfx-series/release-notes/ex-ocx-qfx-series-junos-release-notes-14.1X53-D35.pdf Page 46. I really does not know about the ACX5048 BU team ... but I think there is a good chance to work too ...
