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 SSM mode.
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.
■
The SSM group range is 232.1.1.0/24.
