rad daemon strange error message

Hi All,
I am trying to setup the rad daemon on a quite complicated configuration. I receive
however a strange error message which I don't understand fully.

The message claims that there is no link local address on the device "vether30". But, as far as I understand
a such address is present with the value "fe80::fce1:baff:fed2:a15%vether30"
(as one can notice in the following log).

Any idea about this problem?

Thanks for your help,

Best regards,
