Poking around looking for more information, I ran across this little tidbit: >From man 7 rtnetlink: rtm_type Route type ----------------------------------------------------------------- RTN_UNSPEC unknown route RTN_UNICAST a gateway or direct route RTN_LOCAL a local interface route RTN_BROADCAST a local broadcast route (sent as a broadcast) RTN_ANYCAST a local broadcast route (sent as a unicast) RTN_MULTICAST a multicast route RTN_BLACKHOLE a packet dropping route RTN_UNREACHABLE an unreachable destination RTN_PROHIBIT a packet rejection route RTN_THROW continue routing lookup in another table This clears up the confusion I had about "anycast" versus "broadcast". Is there a shell tool that will show the route type(s) for a specified address?
