Rpt Establishment Failure Or Source Registration Failure In Ipv6 Pim-Sm - HP A5500 SI Switch Series Configuration Manual

Solution
Verify that a route is available to the RP. Use the display ipv6 routing-table command to determine
1.
whether a route is available on each router to the RP.
Evaluate the dynamic RP information. Use the display pim ipv6 rp-info command to determine
2.
whether the RP information is consistent on all routers. In the case of inconsistent RP information,
configure consistent RP address on all the routers.
Evaluate the static RP configuration. Use the display pim ipv6 rp-info command to determine
3.
whether the same RP address has been configured on all the routers throughout the network.
RPT establishment failure or source registration failure 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 will be unable to receive the advertisements from the C-RP, and the
bootstrap messages of the BSR will not contain the information about that C-RP.
The RP is the core of an IPv6 PIM-SM domain. Make sure that 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
Verify that the routes to C-RPs, the RP and the BSR are available. Use the display ipv6 routing-table
1.
command to determine whether the routes to the RP and the BSR are available on each router and
whether a route is available between the RP and the BSR. Be sure that 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.
Evaluate the RP and BSR information. IPv6 PIM-SM needs the support of the RP and BSR. Use the
2.
display pim ipv6 bsr-info command to determine whether the BSR information is available on each
router, and then use the display pim ipv6 rp-info command to determine whether the RP information
is correct.
View the IPv6 PIM neighboring relationships. Use the display pim ipv6 neighbor command to
3.
determine whether the normal neighboring relationships have been established among the routers.
