PIM-SM non-scoped zone configuration example
Network requirements
• As shown in Figure 50, receivers receive VOD information through multicast. The receiver groups
of different organizations form stub networks, and one or more receiver hosts exist in each stub
network. The entire PIM-SM domain contains only one BSR.
• Host A and Host C are multicast receivers in two stub networks.
• Switch D connects to the network that comprises the multicast source (Source) through VLAN-
interface 300.
• Switch A connects to stub network N1 through VLAN-interface 100 and to Switch D and Switch E
through VLAN-interface 101 and VLAN-interface 102, respectively.
• Switch B and Switch C connect to stub network N2 through their respective VLAN-interface 200,
and to Switch E through VLAN-interface 103 and VLAN-interface 104 respectively.
• VLAN-interface 105 on Switch D and VLAN-interface 102 on Switch E act as C-BSRs and C-RPs.
The C-BSR on Switch E has a higher priority. The multicast group range served by the C-RP is
225.1.1.0/24. Modify the hash mask length to map a certain number of consecutive group
addresses within the range to the two C-RPs.
• IGMPv2 will run between Switch A and N1 and between Switch B/Switch C and N2.
