[OLSR-users] No MPR as Next Hop in Routung Table

[lolo]

Hello all

I was asked some days ago if the MPR were the *only* nodes relaying 
traffic in an OLSR ad hoc network.
I answered yes.
What i did not saw is that a node A which is *not* MPR for node B but is 
a symetric neighbour of node B,
could be the next hop for many destinations in the routing table of node 
B, as long as node A have the status of
MPR for any node C. (Node A is able to generate TC messages)
What could be the "MPRish" relationships between node A, B, C needed for 
such a case to occur ?
For exemple : Node C MPR of both A and B ?

TIA
