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. 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.
Solution
1. Use display ipv6 routing-table to verify that the IPv6 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. Make sure
each C-RP has an IPv6 unicast route to the BSR, the BSR has an IPv6 unicast route to each C-RP, and
each router on the network has IPv6 unicast routes to the C-RPs.
2. Use display ipv6 pim bsr-info to verify that the BSR information exists on each router. Then, use
display ipv6 pim rp-info to verify that the RP information is correct on each router.
3. Use display ipv6 pim neighbor to verify that IPv6 PIM neighboring relationship has been correctly
established among the routers.
