>Description:
When route6d is running, it will delete the site-local routes after about five minutes.
>How-To-Repeat:
Set up a site-local IPv6 address as well as a public one on an interface and enable routing etc (My config snippit follows) and wait five minutes.
The route gets deleted and not logged to /var/log/route.log, but route monitor output shows the PID (812) of route6d deleting the route (log snippit follows).
