Only a client of the MROUTING socket-level API (e.g. mrouted, XORP,
pimdd, pimsd) is able to cause the kernel to enable ALLMULTI on an
interface by itself.
You will need to get a multicast routing daemon of some kind running to
test this. mrouted is OK for testing very simple configurations,
although it has been de-orbitted as far as the 'Net itself is concerned.
