Three kinds of tables affect data transmission. The correlations of them are:
Each multicast routing protocol has its own multicast routing table.
The multicast routing information of all multicast routing protocols is integrated to
form the core multicast routing table.
The core multicast routing table is consistent with the multicast forwarding table,
which is in really in charge of multicast packet forwarding.
Use the command...
display multicast
routing-table [ group-address
[ mask { group-mask |
mask-length } ] |
source-address [ mask
{ group-mask | mask-length } ]
| incoming-interface
{ interface-type
