Huawei V200R001C01 - MSDP Peers Cannot Generate Correct (S, G) Entries

Run the display pim interface interface-type interface-number command on the device to check
whether the interface that forwards multicast data is a receiver's DR.
l If the DR information in the command output is not marked with local, troubleshoot the
involved DR following the preceding steps.
l If the DR information in the command output is marked with local, go to Step 6.
Step 6 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 7.
Step 7 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 that a source 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 8.
Step 8 Check whether the PIM routing table contains correct (S, G) entries.
Run the display pim routing-table command on the device to check whether the PIM routing
table contains (S, G) entries. For details, see Step 1.
Step 9 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
