PIM-SM non-scoped zone configuration example

Network requirements

As shown in Figure 34, VOD streams are sent to receiver hosts in multicast. The receivers of different

subnets form stub networks, and at least one receiver host exist in each stub network. The entire PIM-SM

domain contains only one BSR.

Host A and Host C are multicast receivers in the stub networks N1 and N2.

Ethernet 1/3 on Router D and Ethernet 1/3 on Router E act as C-BSRs and C-RPs. The C-BSR on Router

E has a higher priority. The C-RPs are designated to the multicast group range 225.1.1.0/24. Modify the

hash mask length to map the multicast group range to the two C-RPs.

IGMPv2 runs between Router A and N1, and between Router B, Router C, and N2.
