yes, the MPR idea was a good idea, in theorie.

as i heard, it did not work out at all and made the mesh even more unstable.

i think, the problem was in the way of selecting MPR, but i don't
remember exactly, elektra did a very good explanation that time, some 2
or 3 years ago.

it is quite sad to see that knowledge lost in the current OLSR developer
community.

elektra, could you be so nice and enlight aaron on the topic of problems
with the MPR selection?
