Are you asking about node protection, or path protection?
Both are at varying stages of work - have your favorite cisco sales
folks get in touch with me if you want more info.
You can do a limited path-protection-like thing now by
- configuring 2 tunnels to the same destination
- making sure they don't take the same physical path (this can be
tricky to do large-scale or with any dynamicity (is that a word?))
- configure the "primary path" with
tunnel mpls traffic-eng autoroute metric relative -2
- and the backup path with
tunnel mpls traffic-eng autoroute metric relative -1

path protection is nifty, but IMHO doesn't scale that well. Link and
node protection are far more scalable. There are a few cases where
path protection is useful, but not as many as people seem to think...:)
