The multicast routing tables can be layered as follows:
Each multicast routing protocol has a multicast routing table of itself.
All the multicast routing tables can be summarized into the multicast kernel routing
tables.
The multicast kernel routing tables should keep consistent with the multicast
forwarding tables which actually control the forwarding of the multicast data
packets.
The multicast forwarding tables are mainly used for debugging. Usually, users can view
the multicast kernel routing tables to get the required information.
