Here in L=C3=BCbeck we are currently experimenting with such an IPv6-mesh-o= nly network. Because of BTM-Adv a completely adhoc ip-assignment is possibl= e as long as your mac adresses in your network are unique (as they should b= e). If it were just for communications inside of the mesh without any routi= ng from this mesh to hosts outside of the mesh, you can even use the automa= tically assigned link-local adresses - this is working out of the box in mo= st current operating systems. So basically our intention is to not have the mesh network as an uplink dir= ectly to the internet but more as a dedicated metropolitan area network, a = switched "LAN". In this MAN everyone shall be free to set up VPNs for their= internet gateway / to their home network. Of course this is a trade-off ab= out usability on the other hand as setting up a VPN is not a trivial task f= or "common" people... but don't know what your specific goal is. Could you = expain your intention a little further maybe? We were also running in some trouble with those link-local adresses, not al= l applications seem to support this properly. Therefore we were assigning a= dditional ipv6 unique local addresses with the help of radvd (and limited t= his to the local wifi/ethernet clients on one router with the help of ebtab= les). (this should also be possible with dhcpv6 instead of using radvd thou= gh, I guess) I'm not aware of any routing protocol supporting dynamic, decentral ipv4+6 = internet gatewaying over a ipv6-only mesh network yet. Though there are dis= cussions about how this could be achieved on the BATMAN-Adv side as well. I= 'm also curious about what the Berlin Freifunk guys are up to with NIIT, go= tta have a look at the workshop/discussion during the 26c3. Has anyone hear= d of IVI (or totd) yet? I think this should make routing packets between th= e ipv4 and ipv6 stack possible.
