[Olsr-dev] reduce OLSR bandwidth by tuning emission intervals

My network architecture support: 
 ●  any private IPv4 to any private IPv4
 ●  any private IPv4 to any public IPv4 (with nat)
Due to the restrictions, I don't have the routing overhead.

If you need to support the publics and don't want to run VPN on every node, you have to opt for sending reachability upwards on the VPN link on your exit links. You have BGP in place, so go for it.

For IPv6, I would use dynamic renumbering for public addresses and ULA for private. Today I don't support IPv6, because my providers doesn't provide…

I'll gather something on my network model I can release.

>>> My described network design does't run routing on the tunnel. Each router sets up its own tunnel. So for example a MANET with 20 routers and 5 exit links has 20 tunnels. Average number of tunnel keep-alives on exit link is 4. For MANETs with few exit links, this models doesn't work well. But this becomes less common, I think.
