To do...
View the multicast
boundary information
View the multicast
forwarding table
information
View the multicast routing
table information
View the information of
the multicast static routing
table
View the RPF route

specified multicast source
Clear forwarding entries
from the multicast
forwarding table
Clear routing entries from
the multicast routing table

CAUTION:
The reset command clears the information in the multicast routing table or the
■
multicast forwarding table, and thus may cause failure of multicast
transmission.
When a routing entry is deleted from the multicast routing table, the
■
corresponding forwarding entry will also be deleted from the multicast
forwarding table.
When a forwarding entry is deleted from the multicast forwarding table, the
■
corresponding route entry will also be deleted from the multicast routing table.
Network requirements
PIM-DM runs in the network. All switches in the network support multicast.

Displaying and Maintaining Multicast Routing and Forwarding

Use the command...
display multicast boundary [ group-address
[ mask | mask-length ] ] [ interface
interface-type interface-number ]
display multicast forwarding-table
[ source-address [ mask { mask | mask-length } ] |
group-address [ mask { mask | mask-length } ] |
incoming-interface { interface-type
interface-number | register } |
outgoing-interface { { exclude | include |
match } { interface-type interface-number |
register } } | statistics ] * [ port-info ]
display multicast routing-table
[ source-address [ mask { mask | mask-length } ] |
group-address [ mask { mask | mask-length } ] |
incoming-interface { interface-type
interface-number | register } |
outgoing-interface { { exclude | include |
match } { interface-type interface-number |
register } } ] *
display multicast routing-table static
[ config ] [ source-address { mask-length |
mask } ]
display multicast rpf-info source-address
[ group-address ]
reset multicast forwarding-table
{ { source-address [ mask { mask | mask-length } ]
| group-address [ mask { mask | mask-length } ] |
incoming-interface { interface-type
interface-number | register } } * | all }
reset multicast routing-table
{ { source-address [ mask { mask | mask-length } ]
| group-address [ mask { mask | mask-length } ] |
incoming-interface { interface-type
interface-number | register } } * | all }
