1-30SA Message Filtering ConfigurationNetwork requirementsz Three PIM-SM domains exist in the network, and OSPF runs within and among the domains toprovide unicast routing.z Configure respective Loopback 0 of Switch A, Switch C and Switch D as a C-BSR and C-RP in therespective PIM-SM domain.z Set up an MSDP peering relationship between Switch A and Switch C and between Switch C andSwitch D.z Source 1 sends multicast data to multicast groups 225.1.1.0/30 and 226.1.1.0/30, and Source 2sends multicast data to multicast group 227.1.1.0/30.z Configure SA message filtering rules so that receivers Host A and Host B can receive only themulticast data addressed to multicast groups 225.1.1.0/30 and 226.1.1.0/30, while Host canreceive only the multicast data addressed to multicast groups 226.1.1.0/30 and 227.1.1.0/30.Network diagramFigure 1-8 Network diagram for SA message filtering configurationLoop0Vlan-int102Vlan-int102Device Interface IP address Device Interface IP addressSource 1 — 10.110.3.100/24 Switch C Vlan-int300 10.110.4.1/24Source 2 — 10.110.6.100/24 Vlan-int104 10.110.5.1/24Switch A Vlan-int100 10.110.1.1/24 Vlan-int101 192.168.1.2/24Vlan-int102 10.110.2.1/24 Vlan-int103 192.168.2.2/24Vlan-int101 192.168.1.1/24 Loop0 2.2.2.2/32Loop0 1.1.1.1/32 Switch D Vlan-int400 10.110.6.1/24Switch B Vlan-int200 10.110.3.1/24 Vlan-int500 10.110.7.1/24Vlan-int102 10.110.2.2/24 Vlan-int104 10.110.5.2/24Vlan-int103 192.168.2.1/24 Loop0 3.3.3.3/32Configuration Procedure1) Configure IP addresses and unicast routing
