Hi AB, 

As Chris said, reactive/proactive approach has nothing to do with stability you mentioned. It’s totally a router’s internal process — the outsiders won’t even know the difference.

While we know that OLSRv2 is a proactive protocol so if we use source routing as in this protocol it should do only reactive calculation that makes it stable in the dynamic-networks like manet. IMHO, using reactive and proactive independently seems strange in manet routing environment. I advise to look into conditions of its theories because it seems that this multipath routing in for fixed-wireless-networks not for manets.
