When you have a critical link that needs to be protected from extended packet loss, it is possible to pre-establish a MPLS TE tunnel (aka NHOP) routed around the link so traffic can be immediately rerouted after the link goes down, by simply start using the MPLS TE label instead of regular label, without having to wait for routing to converge. This method is known as Fast Reroute with Link Protection and we go through the setup and configuration in this video. We will also perform failover test so you can see this in action.

and i dont know the problem should i change the IOS or i have a problem in my config ??????!!!!

Hmm.. This is hard to say. If you are sure on your config, definitely try different IOS, either upgrade or downgrade to 12.4 as it is not unusal to be IOS related issue.
