Ok. It's better now. I am not getting any update from bad source, other than
"sourced from one of our addresses". The cause for the bad source was that I
didn't have vlan and port assignment correctly configured.
However, I am still not getting "Invalid Authentication", which I was told I
should be getting without setting the lifetime..
RIP event debugging is on
