But in some circumstances, the multicast network topology differs from that of unicast network or some routers in the network supports unicast only. Then you can configure static multicast routes to offer different transferring paths for multicast and unicast data separately. Notice the following two considerations:  The static multicast routing functions only to affect the RPF check, but not to direct the forwarding of the multicast data, so it is also called RPF static routing;  The static multicast routing only functions in the configured multicast router. It won't be broadcasted or imported into other routers in any way. The static multicast routing is an important foundation for the RPF check. In the RPF check process, with static multicast routing configured, the router will choose one as the RPF route after comparing the optimal unicast route and the static multicast route selected respectively from the unicast routing table and the static multicast routing table. Figure 11-26 Static Multicast Routing As shown in Figure 11-26, when no static multicast routing entry is configured, the RPF neighbor of Router C to the multicast source is Router A. The multicast packets sent from Source will be 242

11.5 Static Mroute
When the multicast network topology is the same as that of the unicast network, receivers can
receive the multicast data through the unicast route. But in some circumstances, the multicast
network topology differs from that of unicast network or some routers in the network supports
unicast only. Then you can configure static multicast routes to offer different transferring paths for
multicast and unicast data separately. Notice the following two considerations:
The static multicast routing functions only to affect the RPF check, but not to direct the
forwarding of the multicast data, so it is also called RPF static routing;
The static multicast routing only functions in the configured multicast router. It won’t be
broadcasted or imported into other routers in any way.
The static multicast routing is an important foundation for the RPF check. In the RPF check
process, with static multicast routing configured, the router will choose one as the RPF route after
comparing the optimal unicast route and the static multicast route selected respectively from the
unicast routing table and the static multicast routing table.

As shown in Figure 11-26, when no static multicast routing entry is configured, the RPF neighbor
of Router C to the multicast source is Router A. The multicast packets sent from Source will be
