PIM-SM admin-scoped zone configuration example
Network requirements
As shown in Figure 45:
• 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. Router B, Router C, and
Router 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 the multicast group 224.1.1.1. Host C is a multicast receiver for the
m u l t i c a s t g r o u p 224 .1.1.1.
• GigabitEthernet 2/1/2 of Router B acts as a C-BSR and a C-RP for admin-scoped zone 1, and
GigabitEthernet 2/1/1 of Router D acts as a C-BSR and a C-RP for admin-scoped zone 2, and both
of the two interfaces are designated to the multicast group range 239.0.0.0/8. GigabitEthernet
2/1/1 of Router 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 Router A, Router E, Router I, and the receivers that directly connect to them,
respectively.
