I think B) is correct too, R1 keeps using that path.

I'm a bit confused about the LDP-Sync timer. Does R3 really start it after recovering the session? That seems tricky.

I practiced a similar question where R1 kept using the tunnel until the sync feature was disabled, so I think B is true.

I think option C sounds off because I recall that routers usually advertise the best metric, not the maximum.

I remember something about LDP-Sync, but I'm not sure if R1 would keep using the tunnel after R3 recovers.
