can NNHOP expand to more than on hop ?

Hi,

Regard NNHOP, at headend rsvp label of the whole path is being recorded. so
headend knows about all labels of the path.

Q1: knowing all labels of the path , does NNNHOP works? how about NNNNHOP?
if it knows that MP expects which label, it can push to the label stack
,right? I configured it and it doesnt work though.

Q2: given that above doesnt work, so how does PLR knows which label to use
for the backup NNHOP tunnel? just a label on recorded path that is 2 hops
away? Is that how it determines the label?

Cheers,

JEremy
