PIM-SM admin-scoped zone configuration example
Network requirements
As shown in Figure 33, the 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-scoped zone. Router
B, Router C, and Router D are ZBRs of the three domains, respectively.
Source 1 and Source 2 send different multicast informa t io n t o m u l t i c a s t g ro u p 239.1.1.1. H o s t A r e c eiv e s
the multicast information from Source 1 only, and Host B receives the multicast information from Source
2 only. Source 3 sends multicast information to multicast group 224.1.1.1. Host C is a multicast receiver for
this multicast group.
Serial 2/1 of Router B acts as a C-BSR and C-RP of admin-scoped zone 1, which serve the multicast group
range 239.0.0.0/8. Serial 2/1 of Router D acts as a C-BSR and C-RP of admin-scoped zone 2, which
also serve the multicast group range 239.0.0.0/8. Serial 2/1 of Router F acts as a C-BSR and a C-RP of
the global-scoped zone, which serve all the multicast groups other than those in the 239.0.0.0/8 range.
IGMPv2 runs between Router A, Router E, Router I, and their respective receivers.
