If you start a multicast router connected to eth0.12, and if that
router originates IGMPv2 Query messages, then eth0.12 will
automatically switch to using IGMPv2. Hence, make sure that the
IGMPv2 Query messages from the XORP router are reaching your client
running on eth0.12. Tcpdump is your friend here.
