Thanks everyone for your help/examples. I tried this with an all-JUNOS topology and node-link-protection worked. One important thing to note is that a complete Route-Record on the primary lsp seems required for node-protection. Also, 'set protocols rsvp [interface] link-protection' is required only on the primary path interface as mentioned earlier by others.
