how bypass LSP of link-protection is created ?

Hi,

I think that LSP bypass of link-protection should follow the IGP if the link down. But in my case, it doesn't.

My configuration is very simple. I just set link-protection in all interfaces (on all routers).

But when i check the bypass LSP for protecting interface ge-0/0/0 on R1, it does not follow the IGP path: R1->R2->R3->R4, it follow the futher path through: R1->R5->R6->R2->R3->R4. I checked some others bypass LSP, almost of them still don't follow the IGP path. 

Thanks for any explanations.
