[OLSR-users] Gould not find global IPv6 address (i.e. olsr becomes blind ; )

[Andreas Tønnesen]

The interface is configured to use a site-local address(as stated in
the debug output"IPv6 addrtype            : site-local"). There is
no site-local addresses configured on the interface.
To use global addresses set
Ip6AddrType         global
in the interface section in the configuration file.
