If/when supplementing with RSVP LSPs isn't an option for you, you might also wish to consider enabling Loop-Free Alternates (LFA) for your IGP along with an exported load-balance policy on each Juniper device to (potentially) speed up convergence in the event of a failure. Having a backup next-hop pre-installed in the forwarding plane has helped me greatly in areas where RSVP w/FRR isn't available/used. Its scope is local, so there's no dependency on having it configured on *every* router in your network. Your mileage may vary depending on what your topology looks like (ie. whether LFA can find a loop-free backup or not).
