Few thought..
First: of all you need to remove this command because it's preventing RSVP route form being install into inet.3
no-install-to-address
If you don't resolve BGP next-hop with rsvp route in inet.3, you will not be able to use your strict-path LSP.
Second: I don't understand the reson of applying export policy to the forwarding table. Even if you don't apply the policy and simply remove no-install-to-address, it will work fine and your traffic will traverse across strict-path LSP
