[Olsr-users] [Fwd: Re: Received HNA from NON SYM neighbor]

Tue Nov 25 00:01:05 CET 2008

Hi Aaron,

Actually, as it happens, this time around I'm using olsrd_dyn_gw plugin on
my gateway node rather than a Hna4 0.0.0.0 0.0.0.0 route

so you could be right - I'll test again in a minute with the Hna entry and
NOT using the dyn_gw plugin
