    Hi Gabor,
    I am not speaking of any particular draft, I am speaking of families 
of solutions - rerouting decision made entirely within router adjacent 
to failure vs. router close to failure point communicating with other 
routers to reroute traffic remotely.
    All FN drafts fall into category of remote notification; LFA, 
not-via and other works FN being compared with fall into category of 
local repair.

Anton

Based on that mail, I think you are mixing things; there you were writing about draft-kini-ospf-fast-notification-01, while Andras is speaking about draft-csaszar-ipfrr-fn-00. While the first one is just wanting to increase the speed of LSA advertisement, the second one is doing real FRR using only data plane. Am I right, were you speaking about the former draft?
