[Xorp-users] running IP multicast using xorp with click

hi Pavlin,
I have some quick followup questions for you: for the control plane, xorp 
supports the following:
- IGMP group management protocol: for group registration and management
- PIM-SM: for constructing/compute multicast tree, and construct fwd table 
for multicast <destination multicast group address, interfaces to forward>

and, the only interface between xorp and Click (or whatever data plane 
environment) is the multicast forward table, is it correct?

so that the data plane (of Click) has to support: multicast forwarding. when 
receiving packets destinated to multicast group address, it looks up the 
forwarding table, and copy the packets through multiple interfaces for the 
group. is it also correct?

thanks,
Yaping
