z 

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. 

z 

Host A and Host C are multicast receivers in two stub networks. 

z 

Switch D connects to the network that comprises the multicast source (Source) through 

VLAN-interface 300. 

z 

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.  

z 

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. 

z 

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. 

z 

IGMPv2 is to run between Switch A and N1, and between Switch B/Switch C and N2.
