Operation Manual – Multicast ProtocolH3C S3610&S5510 Series Ethernet Switches Chapter 8 Multicast Policy Configuration8-113) Configuring a multicast static route# Configure a multicast static route on Switch C, and configure the address of the RPFcheck interface to be 192.168.3.2/24.[SwitchC] ip rpf-route-static 10.220.5.100 255.255.255.0 192.168.3.24) Verifying the configuration# Before the configuration of a multicast static route, Receiver can normally receivemulticast data from Source1, and Switch C can receive multicast data from Switch B.The RPF information on Switch C is as follows:[SwitchC] display multicast rpf-info 10.110.5.100RPF information about source 10.110.5.100:RPF interface: Vlan-interface100Referenced route/mask: 10.110.5.0/24Referenced route type: igpRoute selection rule: preference-preferredLoad splitting rule: disable# View RPF neighbor information after configuring a multicast static route. You will findthat the RPF upstream neighbor has changed. This is because the multicast staticrouter is functioning. The RPF information on Switch C is as follows:[SwitchC] display multicast rpf-info 10.220.5.100RPF information about source 10.220.5.100:RPF interface: Vlan-interface300Referenced route/mask: 10.220.5.0/24Referenced route type: unicastRoute selection rule: preference-preferredLoad splitting rule: disable8.6 Troubleshooting Multicast Policies8.6.1 Multicast Static Route FailureI. SymptomNo dynamic routing protocol is enabled on the routers, and the physic status and linklayer status of interfaces are both Up, but the multicast static route fails.II. Analysisz If the multicast static route is not configured or updated correctly to match thecurrent network conditions, the route entry does not exist in the multicast staticrouting table and multicast routing table.z If the optimal route if found, the multicast static route may also fail.
