Gabor Those are very reasonable questions, however it is quite a difficult problem to address since we need real topologies and these are only available under non-disclosure from network operators. This has historically been a particular problem for the academic IPFRR researchers.
Section 7.3 of the draft is a survey of a number of operational networks that we have analyzed. Stewart (as author) On 01/06/2012 09:34, Gábor Sándor Enyedi wrote:
I conditionally support it. I think we need several further studies; e.g. what are the RLFA friendly topologies, how can I improve my network to keep up full coverage (and what extra cost that has), what is the bidirectional coverage of RLFA (if path cannot be protected in either directions, the route is not protected), how many targeted LDP sessions are needed when the network is not the one operated by Stephane Litkowski, what is the coverage when there was a failure in our network previously and so on.

There is known IPR associated with it on file ( https://datatracker.ietf.org/ipr/1770/ ) This draft presents a solution for IP/LDP fast-reroute that does not guarantee 100% coverage but can substantially improve coverage over LFAs. We would like to initiate a WG poll to determine whether to adopt draft-shand-remote-lfa. We are, of course, interested in opinions and reasoning rather than simple yes/no.
