Three kinds of tables affect data transmission. Their correlations are as follows:
z Each multicast routing protocol has its own multicast routing table.
z The multicast routing information of all multicast routing protocols is integrated to
form the core multicast routing table.
z The core multicast routing table is consistent with the multicast forwarding table,
which is actually in charge of multicast packet forwarding.
