5.7.2 PIM-SM Configuration Example

I. Network requirements
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 domain operates in the sparse mode (not
divided into different BSR admin-scope regions).
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.
Switch E connects to Switch A, Switch B, Switch C and Switch D, and its
VLAN-interface 102 interface acts a C-BSR and a C-RP, with the range of
multicast groups served by the C-RP being 225.1.1.0/24.
IGMPv2 is to run between Switch A and N1, and between Switch B/Switch C and
N2.
