Could you specify what exactly you are trying to achieve?

If you have a XORP application that has opened an UDP socket for
example, that application can use socket4/0.1/udp_join_group XRL
(see xrl/interfaces/socket4.xif) to join a multicast group.
There are similar XRLs for the raw IP and raw link interface:
join_multicast_group in fea_rawpkt4.xif and join_multicast_group
in fea_rawlink.xif .

In all cases there must be an application (XORP client) that is
listening for the packets received for the joined multicast group,
but I have the feeling this is not what you are looking for.
