Mpls Session protection - SP

Hi GS,

I've been creating my own mpls labs while studying and obviously came across
session protection. Standard Session Protection with the use of mpls ldp
session protect for/duration etc I fully understand and can comprehend.

So here's my question, If I do NOT enable session protection, But configure
targeted hellos between two directly connected neighbors with mpls ldp neigh
X.X.X.X targeted and mpls ldp disc targeted accept, I get basically the same
results.
Ie when the directly link goes down the session is still there, Label
database is still populated etc.

From my testing the reconvengence times etc are the same using both methods.
The only difference I can see is the ability to put a duration timer on
session protection and that show mpls ldp neigh X det specifically mentions
Session protection.

Have I missed something? or Can you infact use targeted hellos as a form of
session protection as my tests have shown?

Cheers.
Josh
