598 CHAPTER 31: MSDP C ONFIGURATIONc When the multicast source S1 in the PIM-SM domain sends multicast information,the receivers attached to SwitchD can receive the multicast information and canview the PIM routing information on the switch by using the display pimrouting-table command. For example, the following PIM routing information isdisplayed on SwitchC and SwitchD.[SwitchC] display pim routing-tableTotal 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 ACTUpTime: 00:10:20Upstream interface: Vlan-interface200RPF neighbor: Vlan-interface200Downstream interface(s) information:Total number of downstreams: 11: Vlan-interface110Protocol: pim-sm, UpTime: 00:10:20, Expires: 00:03:10[SwitchD] display pim routing-tableTotal 0 (*, G) entry; 1 (S, G) entry(10.110.5.100, 225.1.1.1), RP: 10.1.1.1Protocol: pim-sm, Flag: SPT ACTUpTime: 00:03:32Upstream interface: Vlan-interface101RPF neighbor: 192.168.3.2Downstream interface(s) information:Total number of downstreams: 11: Vlan-interface100Protocol: pim-sm, UpTime: 00:03:32, Expires: -3 Configure an MSDP peera 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] quitb 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] quitc You can use the display msdp brief command to view the MSDP peerrelationship established between the switches.
