[Olsr-users] Received HNA from NON SYM neighbor

[Derek C]

Hi guys,

There is something wrong with that config I was using (as per bottom of
the email).

When I cut down my olsrd.conf to nearly nothing I get my default route ok.

I'm not sure where the problem is yet (fisheye maybe?).  I've have to add
items back in one by one until I find the problem.

Anyway - I'm back working with OLSRd which makes me very happy :)

Derek
