l If the DR information in the command output is marked with local, go to Step 7.
Step 7 Check whether a multicast boundary is configured on the interface.
Run the display current-configuration interface interface-type interface-number command
on the device to check whether a multicast boundary is configured on the interface.
l If the configuration of the interface contains multicast boundary, it indicates that a
multicast boundary is configured on the interface. Then you need to run the undo multicast
boundary { group-address { mask | mask-length } | all command to delete the configuration
of the multicast boundary or re-plan the network to ensure that no multicast boundary is
configured on the RPF interface or the RPF neighboring interface.
l If no multicast boundary is configured on the interface, go to Step 8.
Step 8 Check whether a source policy is configured.
Run the display current-configuration configuration pim command to view the current
configurations in the PIM view.
l If the configuration contains source-policy acl-number, it indicates a source-based
filtering rule is configured. If the received multicast data is denied by the ACL rule, the
multicast data is discarded. Then you need to run the undo source-policy command to
delete the configuration of the ACL rule or reconfigure an ACL rule to ensure that
demanded multicast data can be normally forwarded.
l If no source policy is configured, go to Step 9.
Step 9 Check whether the PIM routing table contains correct (*, G) entries.
Run the display pim routing-table group-address command on the device to check whether
the PIM routing table contains correct (*, G) entries. For details, see Step 1.
If the fault persists after the preceding troubleshooting procedures are complete, go to Step 10.
Step 10 Collect the following information and contact Huawei technical support personnel.
l Results of the preceding troubleshooting procedure
l Configuration files, log files, and alarm files of the devices
