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.
III. Solution
1)
Check whether routes to C-RPs, the RP 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.
