I think it's right but, this way, you're not using the optimized routing 
policy followed by the OLSR protocol. So, I think you should evaluate if 
you really need it or you'd better use a network simulator to create 
"strange" scenarios...

>2)is it possible to prevent the two endpoints of the ring to act as MPR?
As far as I know, it's not possible. The choice of which node has to 
behave as an MPR is made by the daemon
