Hello,
  Are there any IETF standard/document  for IGP/OSPF
fast reroute as has been presented by alex zinin and
chenigz in their presentation :"IGP Fast Reroute" ,
slides can be found at

http://www.packetdesign.com/news/presentations.html

This seems to be a good alternative to IGP fast
convergence, to achive sub-second re-routing wit IGPs,
by generating a two(or a fixed number of) best routes
rather than one best route.

If there are any IETF standards on this or, any work
in progress in IETF, please point me to the documents.
or, is this completely implementation specific.

Are there any vendor /academic implementation that
supports IGP/OSPF fast rerouting as presented above??

thanks,
kajol.
