# Enable multicast on SwitchC and enable PIM-SM on all interfaces. The
configuration procedures on other switches are similar to that on SwitchC. The
details are omitted here.

# Configure the same Loopback10 interface address on SwitchC and SwitchD and
configure the locations of C-BSRs and C-RPs. The configuration procedure on
SwitchD is similar to that on SwitchC. The details are omitted here.
[SwitchC] pim

[SwitchC-pim] c-rp loopback 10
[SwitchC-pim] quit
# When the multicast source S1 in the PIM-SM domain sends multicast
information, receivers on Switch D can receive multicast information. Carry out the
display pim routing-table command to view PIM routes on the switch. The
information about PIM routes on Switch C and Switch D is displayed as follows:
