PIM-SM admin-scoped zone configuration example
Network requirements
As shown in
, receivers receive VOD information through multicast. The entire PIM-SM domain
is divided into admin-scoped zone 1, admin-scoped zone 2, and the global zone. Switch B, Switch C,
and Switch D are ZBRs of these three zones, respectively.
Source 1 and Source 2 send different multicast information to multicast group 239.1.1.1. Host A receives
the multicast information from only Source 1, and Host B receives the multicast information from only
Source 2. Source 3 sends multicast information to multicast group 224.1.1.1. Host C is a multicast receiver
for this multicast group.
VLAN-interface 101 of Switch B acts as a C-BSR and a C-RP of admin-scoped zone 1 to provide services
for the multicast group range 239.0.0.0/8. VLAN-interface 104 of Switch D acts as a C-BSR and a C-RP
of admin-scoped zone 2 to provide services for the multicast group range 239.0.0.0/8. VLAN-interface
109 of Switch F acts as C-BSRs and C-RPs of the global-scoped zone to provide services for all the
multicast groups other than those in the 239.0.0.0/8 range.
IGMPv2 runs between Switch A, Switch E, Switch I and their respective receivers.
