the receivers attached to SwitchD can receive the multicast information and can
view the PIM routing information on the switch by using the display pim
routing-table command. For example, the following PIM routing information is
displayed on SwitchC and SwitchD.

a Configure an MSDP peer on Loopback0 on SwitchC.
[SwitchC] msdp
[SwitchC-msdp] originating-rp loopback0
[SwitchC-msdp] peer 2.2.2.2 connect-interface loopback0
[SwitchC-msdp] quit
b Configure an MSDP peer on Loopback0 on SwitchD.
[SwitchD] msdp
