 Configuration Procedure  Configure Switch A: Step Operation 1 Configure interface. 2 Configure routing protocol. 3 Enable multicast routing and PIM SM. 4 Configure candidate BSR and candidate RP. Description Configure IP addresses and subnet masks of VLAN interfaces 1, 2 and 3 on Routing→ Interface→Interface Config page. Configure the routing entries via static route or dynamic routing protocol like OSPF, and make sure all the switches can communicate with each other and update the routing information through a unicast routing protocol dynamically. Enable multicast routing on Multicast Routing→Global Config page. Enable PIM SM on VLAN interfaces 1, 2 and 3 on Multicast Routing→PIM SM→PIM SM Interface page. Configure VLAN interface 1 as candidate BSR on Multicast Routing→PIM SM→BSR page. Configure VLAN interface 1 as candidate RP on Multicast Routing→PIM SM→RP page.  Configure Switch B and C: Step Operation Description 1 Configure interface. Configure IP addresses and subnet masks of VLAN interfaces 2, 3, 4 and 5 on Routing→ Interface→Interface Config page. 2 Configure routing protocol. Configure the routing entries via static route or dynamic routing protocol like OSPF, and make sure all network can communicate with each other. 3 Enable multicast routing and PIM SM. Enable multicast routing on Multicast Routing→Global Config page. Enable PIM SM on VLAN interfaces 2, 3, 4 and 5 on Multicast Routing→PIM SM→PIM SM Interface page. 4 Enable IGMP. Enable IGMP on the VLAN interfaces 4 and 5 which connect to the receivers on Multicast Routing→IGMP→Interface Config page. 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. 261

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.
