Procedure
l Run the display multicast boundary [ group-address [ mask | mask-length ] ]
[ interface vlanif vlan-id ] command to check the information about the multicast boundary
configured on the interface.
l Run the display multicast forwarding-table [ group-address [ mask { group-mask |
group-mask-length } ] | source-address [ mask { source-mask | source-mask-length } ] |
incoming-interface { interface-type interface-number | register } | outgoing-interface
{ { include | exclude | match } { interface-type interface-number | register | none } } |
statistics | slotslot-number ]
*
command to check the information about the multicast
forwarding table.
l Run the display multicast routing-table [ group-address [ mask { group-mask | group-
mask-length } ] ] [ source-address [ mask { source-mask | source-mask-length } ] ]
[ incoming-interface { interface-type interface-number | register } ] [ outgoing-
interface { include | exclude | match } { interface-type interface-number | register |
none } ] command to check the information about the IP multicast routing table.
l Run the display multicast routing-table static [ config ] [ source-address { mask-
length | mask } ] command to check the information about the static multicast route.
l Run the display multicast rpf-info source-address [ group-address ] command to check
the information about the RPF route.

6.8.5 Debugging Multicast Forwarding and Routing
Context
CAUTION
Debugging affects the performance of the system. So, after debugging, run the undo debugging
all command to disable it immediately.
When a multicast fault occurs, run the following debugging commands in the user view to locate
the fault.
Procedure
l Run the debugging mfib all or debugging mfib { no-cache | module | packet | register
| route | sync | upcall | wrong-iif } [ advanced-acl-number ] [ slot slot-number ] command
to enable debugging of multicast forwarding.
l Run the debugging mrm { all | event | packet [ advanced-acl-number ] | route [ advanced-
acl-number ] } command to enable debugging of multicast routing.
