• In addition, if the BSR does not have a unicast router to a C-RP, it will discard the C-RP-Adv messages
from that C-RP, and therefore the bootstrap messages of the BSR will not contain the information of
that C-RP.
• The RP is the core of a PIM-SM domain. Make sure that the RP information on all routers is exactly
the same, a specific group G is mapped to the same RP, and unicast routes are available to the RP.
Solution
1. Check whether routes to C-RPs and the BSR are available. Carry out the display ip routing-table
command to check whether routes are available on each router to the RP and the BSR, and whether
a route is available between the RP and the BSR. Make 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.
2. Check the RP and BSR information. PIM-SM needs the support of the RP and BSR. Use the display
pim bsr-info command to check whether the BSR information is available on each router, and then
use the display pim rp-info command to check whether the RP information is correct.
3. View PIM neighboring relationships. Use the display pim neighbor command to check whether the
normal PIM neighboring relationships have been established among the routers.
