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.
