I just noticed that the default preference when irdp is enabled = 0. This
means that hosts shouldn't use this router as their gateway (or only as a
last resort - I'm not 100% sure). So, in the lab, if irdp has to be
configured, it may be necessary to set the preference to get the points
assigned to this task.
