VOD streams are sent to receiver hosts in multicast. The entire PIM-SM domain is divided into
admin-scoped zone 1, admin-scoped zone 2, and the global-scoped zone. Switch B, Switch C,
and Switch D are ZBRs of the three zones, respectively.
•
Source 1 and Source 2 send different multicast data to the multicast group 239.1.1.1. Host A
receives the multicast data only from Source 1, and Host B receives the multicast data only
from Source 2. Source 3 sends multicast data to multicast group 224.1.1.1. Host C is a
multicast receiver for the multicast group 224.1.1.1.
•
VLAN-interface 101 of Switch B acts as a C-BSR and a C-RP for admin-scoped zone 1, and
VLAN-interface 105 of Switch D acts as a C-BSR and a C-RP for admin-scoped zone 2. Both of
the two interfaces are designated to multicast group range 239.0.0.0/8. VLAN-interface 109 of
Switch F acts as a C-BSR and a C-RP for the global-scoped zone, and is designated to all the
multicast groups that are not in the range 239.0.0.0/8.
•
IGMPv2 runs between Switch A, Switch E, Switch I, and the receivers that directly connect to
them, respectively.
