Yep, it does. According to man routed, it uses the Internet Router
Discovery Protocol to find other routers to talk to. This is done using
ICMP broadcast as soon as routed starts up. Neither of my FreeBSD boxes
need to run routed apart from routing between the ethernet and PPP link,
but there doesn't seem to be a global "use static routes only" switch to
routed (at least from my skimming of the man page).

Thanks to all for the info.
