[Olsr-dev] olsrd dynamic hna

[Gioacchino Mazzurco]

we have a problem!

olsrmain_load_config("/tmp/olsr.conf");

does not refresh hna6 but simply add all hna6 present on the file

then from

Hna6
{
  0::ffff:0AAE:0000 123
  0::ffff:0AAE:0021 125
  fec0:0015:6DD4:F7D1:0000:0000:0000:0000 64
  fec0:0015:6DD5:F7D1:0000:0000:0000:0000 64
}


 we obtain duplicated entry like this

Table: HNA
Destination     Gateway
fec0:15:6dd5:f7d1::/64  fd7d:d7bb:2c97:dec3:0:15:6dd4:f7d1
fec0:15:6dd4:f7d1::/64  fd7d:d7bb:2c97:dec3:0:15:6dd4:f7d1

fec0:15:6dd4:f7d1::/64  fd7d:d7bb:2c97:dec3:0:15:6dd4:f7d1
::ffff:10.174.0.0/123   fd7d:d7bb:2c97:dec3:0:15:6dd4:f7d1
fec0:15:6dd5:f7d1::/64  fd7d:d7bb:2c97:dec3:0:15:6dd4:f7d1
fec0:15:6dd4:f7d1::/64  fd7d:d7bb:2c97:dec3:0:15:6dd4:f7d1
