HP MSR4080 Configuration Guide

144
Multicast data is abnormally terminated on an intermediate
router
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 multicast data but does not create
an (S, G) entry in the PIM routing table.
Solution
To resolve the problem:
1. Use display current-configuration to verify the multicast forwarding boundary settings. Use
multicast boundary to change the multicast forwarding boundary settings to make the
multicast packet able to cross the boundary.
2. Use display current-configuration to verify the multicast source policy. Change the ACL rule
defined in the source-policy command so that the source/group address of the multicast data
can pass ACL filtering.
3. If the problem persists, contact Hewlett Packard Enterprise Support.
An RP cannot join an SPT in PIM-SM
Symptom
An RPT cannot be correctly built, or an RP cannot join the SPT toward the multicast source.
Solution
To resolve the problem:
1. Use display ip routing-table to verify that a unicast route to the RP is available on each router.
2. Use display pim rp-info to verify that the dynamic RP information is consistent on all routers.
3. Use display pim rp-info to verify that the same static RPs are configured on all routers on the
network.
4. If the problem persists, contact Hewlett Packard Enterprise Support.
An RPT cannot be built or multicast source registration fails in
PIM-SM
Symptom
The C-RPs cannot unicast advertisement messages to the BSR. The BSR does not advertise BSMs
containing C-RP information and has no unicast route to any C-RP. An RPT cannot be correctly
established, or the source-side DR cannot register the multicast source with the RP.
Solution
To resolve the problem:
1. Use display ip routing-table on each router to view routing table information. Verify that
unicast routes to the C-RPs and the BSR are available on each router and that a route is
available between each C-RP and the BSR.
2. Use display pim bsr-info to verify that the BSR information exists on each router.
3. Use display pim rp-info to verify that the RP information is correct on each router.
4. Use display pim neighbor to verify that PIM neighboring relationship has been correctly
established among the routers.
