An RP cannot join an SPT in IPv6 PIM-SM

Symptom

An RPT cannot be correctly built, or an RP cannot join the SPT toward the IPv6 multicast source.

To resolve the problem:

Use display ipv6 routing-table to verify that an IPv6 unicast route to the RP is available on each device.
Use display ipv6 pim rp-info to verify that the dynamic RP information is consistent on all devices.
Use display ipv6 pim rp-info to verify that the same static RPs are configured on all devices on the network.
If the problem persists, contact Hewlett Packard Enterprise Support.
