The idea is that source address is being used for egress routing, very similar to BRDP. For routing, mechanisms are proposed for source address dependent routing. In fact, Henning implemented it on olsrv2. We did same bug fixing during last meeting. But elements of auto configuration are missing. There is some stuff for homenet around, the idea is that this could be reused for manet's.

Yes. Perhaps keep the (multi-)SGW function for IPv4. Still to be decided to have a olsrd2 plugin or have a separate daemon.
