"0.0.0.0 <http://0.0.0.0/> 10.33.176.1 0.0.0.0 UG
0 0 0 vlan1 (#Def route STILL THERE!!) "
The route stays as you have the entry in HNA4 of vodka3....you can run olsrd
on the wired interface too (thought its not meant for wired)
But what ever is there in HNA4 stays as regardless of if the link is up or
down as olsr is now concerned about wired interfaces and only wireless
(adhoc) interfaces ie is the interfaces you run it on....
Other options are to have some routing protocol to pass on info of the wired
interfaces on to olsr.
