OSPF Remote Loop-Free Alternate (LFA) Fast Reroute (FRR)

Hi Rene,

Regarding the remote LFA version, when you say “P Space: these are the routers that R1 can reach without using the failed link”, do you mean that, under normal operations, these are the routers that R1 is able to reach without using the link that might fail? Otherwise, why not add R4 to the P Space?

The same question applies for the Q Space.

I’ve posted my question here because I don’t see a dedicated discussion for the remote LFA.
