Hi Mark,
  I checked that and didn't find anything. I checked the source and also
noticed that there should be something - apparently these need a debug option
switched on.

In the meantime I noticed there is a difference in the output - the concerend
interface shows TRANSITIVE instead CONFIGURED (I didn't see that at first).

Now I tried to reproduce, and indeed, just doing "ifconfig down; sleep 1;
ifconfig up" has this same effect.

Running rtadvd with -dD now, I get these:

Feb  9 21:36:41 <daemon.notice> edge rtadvd[98594]: <interface nlan_1u becomes
down. stop timer.
Feb  9 21:36:42 <daemon.notice> edge rtadvd[98594]: interface nlan_1u becomes
up. restart timer.

and a lot of output in the debug.log - I'll attach it, one can probably walk
the source with that, but I'm currently busy...
