Description This command enables tunnel selection algorithm based on the tunnel preference level. 
Parameters same-preference-level — In case that the tunnel-spec selection algorithm evaluates into a tunnel 
that is currently unavailable (for example tunnel in a blacklist) then the next elected tunnel, if 
available, will be chosen within the same preference-level as the last attempted tunnel. Only 
when all tunnels within the same preference level are exhausted, the tunnel selection 
algorithm will move to the next preference level.
In case that a new session setup request is received while all tunnels on the same preference 
level are blacklisted, the L2TP session will try to be established on blacklisted tunnels before 
the tunnel selection moves to the next preference level.
