Multicast Data Abnormally Terminated On An Intermediate Router; Rps Unable To Join Spt In Pim-Sm - H3C S5500-EI Series Operation Manual

Operation Manual – Multicast

5) Check that the same PIM mode is enabled on related interfaces. Use the display
pim interface verbose command to check whether the same PIM mode is
enabled on the RPF interface and the corresponding interface of the RPF
neighbor router.
6) Check that the same PIM mode is enabled on all the routers in the entire network.
Make sure that the same PIM mode is enabled on all the routers: PIM-SM on all
routers, or PIM-DM on all routers. In the case of PIM-SM, also check that the BSR
and RP configurations are correct.

7.8.2 Multicast Data Abnormally Terminated on an Intermediate Router

I. Symptom
An intermediate router can receive multicast data successfully, but the data cannot
reach the last hop router. An interface on the intermediate router receives data but no
corresponding (S, G) entry is created in the PIM routing table.
II. Analysis
If a multicast forwarding boundary has been configured through the multicast
boundary command, any multicast packet will be kept from crossing the boundary,
and therefore no routing entry can be created in the PIM routing table.
In addition, the source-policy command is used to filter received multicast
packets. If the multicast data fails to pass the ACL rule defined in this command,
PIM cannot create the route entry, either.
III. Solution
1) Check the multicast forwarding boundary configuration. Use the display
current-configuration command to check the multicast forwarding boundary
settings. Use the multicast boundary command to change the multicast
forwarding boundary settings.
2) Check the multicast filter configuration. Use the display current-configuration
command to check the multicast filter configuration. Change the ACL rule defined
in the source-policy command so that the source/group address of the multicast
data can pass ACL filtering.

7.8.3 RPs Unable to Join SPT in PIM-SM

I. Symptom
An RPT cannot be established correctly, or the RPs cannot join the SPT to the multicast
source.
