• In the case of the static RP mechanism, the same RP address must be configured on all the routers
in the entire network, including static RPs, by means of the static RP command. Otherwise, IPv6
multicast will fail.
Solution
1. Use the display ipv6 routing-table command to verify that a route to the RP is available on each
router.
2. Use the display pim ipv6 rp-info command to verify that the dynamic RP information is consistent
on all routers. In case of inconsistent RP information, configure consistent RP address on all the
routers.
3. Use the display pim ipv6 rp-info command to verify that the same RP address has been configured
on all the routers throughout the network.
RPT cannot be established or a source cannot register in IPv6
PIM-SM
Symptom
C-RPs cannot unicast advertise messages to the BSR. The BSR does not advertise bootstrap messages
containing C-RP information and has no unicast route to any C-RP. An RPT cannot be established correctly,
or the DR cannot perform source registration with the RP.
Analysis
• C-RPs periodically send advertisement messages to the BSR by unicast. If a C-RP does not have a
route to the BSR, the BSR cannot receive the advertisements from the C-RP and the bootstrap
messages of the BSR do not contain the information about that C-RP.
• The RP is the core of an IPv6 PIM-SM domain. Make sure the RP information on all routers is exactly
the same, a specific group is mapped to the same RP, and a unicast route is available to the RP.
Solution
1. Use the display ipv6 routing-table command to verify that routes to the RP and the BSR are
available on each router, and that a route between the RP and the BSR is available. Make sure
each C-RP has a unicast route to the BSR, the BSR has a unicast route to each C-RP, and all the
routers in the entire network have a unicast route to the RP.
2. IPv6 PIM-SM needs the support of the RP and BSR. Use the display pim ipv6 bsr-info command to
verify that the BSR information exists on each router, and then use the display pim ipv6 rp-info
command to verify that the RP information is correct on each router.
3. Use the display pim ipv6 neighbor command to verify that normal neighboring relationship have
been established among the routers.
