In the below topology, in case of failure of link between S and D, S will forward the traffic to A and A will again forward the traffic to S. The reason is very simple the cost of next hop from A to D will be lesser than the alternate path which is A-B-C-D-E. This will create a micro loop till the topology will converge.
So answer is very clear, IP FRR is not the viable option in case of ring and square topology. Instead of LFA, Remote LFA is used when no Local LFA is available and is used to find a remote node which can reach the protected neighbor without traversing the protected link. Remote LFA is primarily used for ring and square based access topologies.
