After VLAN-interface 12 is configured as the PIM domain boundary, LS_D cannot
receive BSR information from LS_B any more; that is, LS_D is excluded from the PIM
domain.
3) Configure LS_C.

7.7 Troubleshooting PIM
Symptom: The router cannot set up multicast routing tables correctly.
Solution: You can troubleshoot PIM according to the following procedure.
Make sure that the unicast routing is correct before troubleshooting PIM.
z Because PIM-SM needs the support of RP and BSR, you must execute the
display pim bsr-info command to see whether BSR information exists. If not, you
must check whether there is any unicast route to the BSR. Then, use the display
pim rp-info command to check whether the RP information is correct. If RP
information does not exist, you must check whether there is any unicast route to
RP.
