9.7.5 Debugging Multicast Routing and Forwarding

When a fault occurs during IPv4 multicast routing management, run the debugging commands
in the user view and locate the fault based on the debugging information. Debugging affects the
performance of the system. So, after debugging, disable it immediately.
Context
Debugging affects the performance of the system. After debugging, run the undo debugging
all command to disable it immediately.
When a fault occurs when multicast is enabled, run the following debugging commands in the
user view to debug multicast routes and to locate the fault.

9.8 Configuration Examples

Examples for configuring static multicast routes and multicast load splitting are provided.

9.8.1 Example for Changing Static Multicast Routes to RPF Routes

Networking Requirements
As shown in
The receiver can receive information from the multicast source. Switch A, Switch B, and Switch
Issue 01 (2011-10-26)
interface { interface-type interface-number | register } | outgoing-interface
{ include | exclude | match } { interface-type interface-number | register | none } ]
[ outgoing-interface-number [ number ] ]
Run the display multicast routing-table static [ config ] [ source-address { mask-
length | mask } ] command in any view to check the static multicast routing table.
Run the display multicast rpf-info source-address [ group-address ] [ rpt | spt ] command
in any view to check the RPF routing information.
CAUTION
Run the following commands in the user view to enable the debugging of multicast
forwarding.
– debugging mfib all
– debugging mfib { no-cache | module | packet | register | route | sync | upcall | wrong-
iif } [ advanced-acl-number ]
Run the debugging mrm { all | event | packet [ advanced-acl-number ] | route [ advanced-
acl-number ] } command in the user view to enable the debugging of multicast routing
management.
Figure 9-1, PIM-DM runs on the network and all the switches support multicast.
