[OLSR-users] olsrd+IPv6 problems: Site-local or global addresses, no routes set

Hi Tobias,

There was a bug in the multicast address configuration for IPv6
in 0.4.8. It is fixed and will be included in 0.4.9. You could try current
CVS to verify that this fixes your problem.
Regarding route propagation you have to use HNA messages to inject
non-olsr routes into the network. However, a plugin can for example
provide dynamic HNA routes(check out the dyn_gw plugin), and a plugin
could be created to inject routes based on other properties.

Hope this helps :-)
