An interface is enabled with source-specific multicast (SSM) mapping and IGMP, and is configured with a static SSM mapping policy. The interface has received IGMPv1 or IGMPv2 Report messages, but the multicast forwarding information base (MFIB) table does not contain the (S, G) entries matching the SSM mapping entries.
Run the display this command in the PIM view to check the current configuration. If the command output displays "ssm-policy", the SSM group address range is redefined on the device.
Run the display acl { acl-number | name acl-name | all } command to check the ACL configuration. Ensure that G is in the SSM group address range. By default, the SSM group address range is 232.0.0.0 to 232.255.255.255.
