> IETF works quite hard to have better support for IPv6 and multi-homing. Homenet, MIF and 6MAN have proposals. 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.
For a community mesh network (non-mobile nodes!) most things might
already be in place.
I have already done some emulations with CORE, using shncpd in a mesh
environment... its nice to see a mesh (including prefixes for the
attached client networks) coming online without configuring anything
at all (expect for the prefix range on the gateway).
IPv4 will still be a problem because its difficult to use
source-specific routing for it (no IPv4 ss-routing support in Linux
kernel, not enough IPv4 private addresses).
I sometimes wonder if it would be acceptable to use a static
configured IPIP tunnel for the IPv4 traffic to the gateway.
