multicast in 2.1

hi,
it seems that 2.1.x requires an explicit route for sending packets to
multicast addresses ? 2.0 worked nicely enough without any such route, but
if I don't do a
route add -net 224.0.0.0 netmask 240.0.0.0 eth0
in 2.1, multicast packets get forwarded to the default gateway (gateway's
ether address in header rather than multicast ether addr).
maybe I didn't look hard enough, but I couldn't find this documented
anywhere.
