c When the multicast source S1 in the PIM-SM domain sends multicast information,
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.
[SwitchC] display pim routing-table
Total 0 (*, G) entry; 1 (S, G) entry
(10.110.5.100, 225.1.1.1), RP: 10.1.1.1 (local)
Protocol: pim-sm, Flag: SPT LOC ACT
UpTime: 00:10:20
Upstream interface: Vlan-interface200
RPF neighbor: Vlan-interface200
Downstream interface(s) information:
Total number of downstreams: 1

[SwitchD] display pim routing-table
Total 0 (*, G) entry; 1 (S, G) entry

3 Configure an MSDP peer
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
[SwitchD-msdp] originating-rp loopback0
[SwitchD-msdp] peer 1.1.1.1 connect-interface loopback0
[SwitchD-msdp] quit
c You can use the display msdp brief command to view the MSDP peer
relationship established between the switches. The following MSDP peer
information is displayed on SwitchC and SwitchD.
[SwitchC] display msdp brief
