The output shows that switches on the SPT path (Switch A and Switch D) have generated the correct
(S, G) entries.

Troubleshooting IPv6 PIM

A multicast distribution tree cannot be correctly built
Symptom
No IPv6 multicast forwarding entries are established on the routers (including routers directly
connected with multicast sources or receivers) in an IPv6 PIM network. This means that an IPv6
multicast distribution tree cannot be correctly built.
Solution
To resolve the problem:
Use display ipv6 routing-table to verify that an IPv6 unicast route to the IPv6 multicast source
1.
or the RP is available.
Use display ipv6 pim interface to verify IPv6 PIM information on each interface, especially on
2.
the RPF interface. If IPv6 PIM is not enabled on the interfaces, use ipv6 pim dm or ipv6 pim
sm to enable IPv6 PIM-DM or IPv6 PIM-SM for the interfaces.
Use display ipv6 pim neighbor to verify that the RPF neighbor is an IPv6 PIM neighbor.
3.
Verify that IPv6 PIM and MLD are enabled on the interfaces that directly connect to the IPv6
4.
multicast sources or the receivers.
Use display ipv6 pim interface verbose to verify that the same IPv6 PIM mode is enabled on
5.
the RPF interface on a router and the connected interface of the router's RPF neighbor.
Use display current-configuration to verify that the same IPv6 PIM mode is enabled on all
6.
routers on the network. For IPv6 PIM-SM, verify that the BSR and C-RPs are correctly
configured.
If the problem persists, contact Hewlett Packard Enterprise Support.
7.
IPv6 multicast data is abnormally terminated on an
intermediate router
Symptom
An intermediate router can receive IPv6 multicast data successfully, but the data cannot reach the
last-hop router. An interface on the intermediate router receives IPv6 multicast data but does not
create an (S, G) entry in the IPv6 PIM routing table.
