>Description:
Because wlan devices are intrinsically unreliable, the error counters increment much faster than routed would like. Then the interface gets marked broken, and routes to it deleted, very quickly. This means that dynamic announcement of wireless networks using the base routed is essentially broken.

A good fix would be a way to tell routed that you know certain interfaces are unreliable and don't care if the error counters become large, or (better) some kind of autodetection of wireless devices. ifi_type reports 802.11 devices as IFT_ETHER, and I didn't look into how to get the media values.
>How-To-Repeat:
Set up a wireless NIC in hostap mode (I used an atheros one), turn on routed, use it for a couple of minutes, and watch it be shut off.
