2.
Use display current-configuration to verify the IPv6 multicast data filter. Change the ACL rule
defined in the source-policy command so that the source/group address of the IPv6 multicast data
can pass ACL filtering.
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.
Analysis
• RPs are the core of an IPv6 PIM-SM domain. An RP provides services for a specific IPv6 multicast
group, and multiple RPs can coexist on a network. Make sure the RP information on all routers is
exactly the same to map a specific IPv6 multicast group to the same RP. Otherwise, IPv6 multicast
forwarding fails.
• If a static RP is configured, use the same static RP configuration on all routers on the entire network.
Otherwise, IPv6 multicast forwarding fails.
Solution
1. Use display ipv6 routing-table to verify that an IPv6 unicast route to the RP is available on each
router.
2. Use display ipv6 pim rp-info to verify that the dynamic RP information is consistent on all routers.
3. Use display ipv6 pim rp-info to verify that the same static RPs are configured on all routers on the
network.
An RPT cannot be built or IPv6 multicast source registration fails
in IPv6 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 IPv6 unicast route to any C-RP. An RPT cannot be correctly
established, or the source-side DR cannot register the IPv6 multicast source with the RP.
Analysis
• The C-RPs periodically send advertisement messages to the BSR by unicast. If a C-RP has no IPv6
unicast route to the BSR, it cannot send advertisement messages to the BSR, and the BSR cannot
advertise BSMs containing the information of the C-RP.
• If the BSR does not have an IPv6 unicast route to a C-RP, it discards the advertisement messages
from the C-RP. Therefore, the BSR cannot advertise BSMs containing the information of the C-RP.
• RPs are the core of an IPv6 PIM-SM domain. Make sure the RP information on all routers is exactly
the same to map a specific IPv6 multicast group to the same RP, and that an IPv6 unicast route to the
RP are available on the routers.
