PIM-SM Non-Scoped Zone Configuration Example
Network requirements
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.
