Multicast Source Discovery Protocol | 633Figure 28-18. MSDP with Anycast RPTo configure Anycast RP:Step Task Command Syntax Command Mode1 In each routing domain that will have multiple RPs serving agroup, create a loopback interface on each RP serving thegroup with the same IP address.interface loopback CONFIGURATION2 Make this address the RP for the group. ip pim rp-address CONFIGURATION3 In each routing domain that will have multiple RPs serving agroup, create another loopback interface on each RP servingthe group with a unique IP address.interface loopback CONFIGURATION4 Peer each RP with every other RP using MSDP, specifying theunique loopback address as the connect-source.ip msdp peer CONFIGURATION5 Advertise the network of each of the unique loopbackaddresses throughout the network.network ROUTER OSPFAS XAS YRP1RP3R1R2R3R41/11/212/11 3/21 3/414/314/11/2PC 1ReceiverPC 3Receiver2/1PC 2SourceRP2OSPFArea 0OSPFArea 0+PIM+IGMP+PIM+IGMPM S D P P e e r s h i pBGP(*, 239.0.0.1), uptime 00:00:09, expires 00:00:00, RP 192.168.0.1, flags: SCJIncoming interface: Null, RPF neighbor 0.0.0.0Outgoing interface list:GigabitEthernet 1/1 Forward/Sparse 00:00:09/Never(10.11.4.2, 239.0.0.1), uptime 00:00:05, expires 00:03:25, flags: CTMIncoming interface: GigabitEthernet 1/21, RPF neighbor 10.11.1.21Outgoing interface list:GigabitEthernet 1/1 Forward/Sparse 00:00:09/Never(10.11.4.2, 239.0.0.1), uptime 00:00:52, expires 00:03:20, flags: FTAIncoming interface: GigabitEthernet 2/1, RPF neighbor 0.0.0.0Outgoing interface list:GigabitEthernet 2/11 Forward/Sparse 00:00:50/00:02:40GigabitEthernet 2/31 Forward/Sparse 00:00:50/00:02:40(*, 239.0.0.1), uptime 00:00:14, expires 00:03:16, RP 192.168.0.3, flags: SIncoming interface: Null, RPF neighbor 0.0.0.0Outgoing interface list:GigabitEthernet 3/41 Forward/Sparse 00:00:14/00:03:16(10.11.4.2, 239.0.0.1), uptime 00:00:14, expires 00:03:17, flags: TMIncoming interface: GigabitEthernet 3/21, RPF neighbor 10.11.0.23Outgoing interface list:GigabitEthernet 3/41 Forward/Sparse 00:00:14/00:03:16(*, 239.0.0.1), uptime 00:00:23, expires 00:00:00, RP 192.168.0.3, flags: SCJIncoming interface: GigabitEthernet 4/31, RPF neighbor 10.11.6.34Outgoing interface list:GigabitEthernet 4/1 Forward/Sparse 00:00:23/Never(10.11.4.2, 239.0.0.1), uptime 00:00:23, expires 00:03:18, flags: CTIncoming interface: GigabitEthernet 4/31, RPF neighbor 10.11.6.34Outgoing interface list:GigabitEthernet 4/1 Forward/Sparse 00:00:23/Never
