MSR系列路由器 RPF检测失败导致组播不可达的经验案例 一、组网: 实际组网如下图,三台MSR路由器启用OSPF,保证全网连通。RouterA与Router分别连接组播源和组播接收PC,希望PC能够正常接收组播数据。 二、问题描述: 如上图组网后,保证路由状态正常,发现并没有出现想要的结果:接收组播的PC并不能收到组播源的组播报文。 三、过程分析: 三台路由器上的简略配置和单播路由表如下: RouterA配置sysnameH3C # interfaceSerial3/0 link-protocolppp ipaddress10.0.0.1255.0.0.0 ospfcost1 # interfaceGigabitEthernet0/0 portlink-moderoute ipaddress20.0.0.1255.0.0.0 pimdm # interfaceGigabitEthernet0/1 portlink-moderoute ipaddress1.0.0.1255.0.0.0 pimdm # ospf1 area0.0.0.0 network1.0.0.00.0.0.255 network20.0.0.00.0.0.255 network10.0.0.00.0.0.255 # <H3C>disiprou RoutingTables:Public Destinations:11Routes:12 Destination/MaskProtoPreCostNextHopInterface 1.0.0.0/8Direct001.0.0.1GE0/1 1.0.0.1/32Direct00127.0.0.1InLoop0 2.0.0.0/8OSPF10210.0.0.2S3/0 10.0.0.0/8Direct0010.0.0.1S3/0 10.0.0.1/32Direct00127.0.0.1InLoop0 10.0.0.2/32Direct0010.0.0.2S3/0 20.0.0.0/8Direct0020.0.0.1GE0/0 20.0.0.1/32Direct00127.0.0.1InLoop0 30.0.0.0/8OSPF10220.0.0.3GE0/0 OSPF10210.0.0.2S3/0 127.0.0.0/8Direct00127.0.0.1InLoop0 127.0.0.1/32Direct00127.0.0.1InLoop0RouterB配置sysnameH3C # interfaceEthernet0/0 portlink-moderoute ipaddress30.0.0.2255.0.0.0 pimdm # interfaceEthernet0/1 portlink-moderoute ipaddress2.0.0.2255.0.0.0 igmpenable # interfaceSerial3/0 fe1clockmaster link-protocolppp ipaddress10.0.0.2255.0.0.0 ospfcost1 # ospf1 import-routedirect area0.0.0.0 network2.0.0.00.0.0.255 network10.0.0.00.0.0.255 network30.0.0.00.0.0.255 # <H3C>disiprou RoutingTables:Public Destinations:11Routes:12 Destination/MaskProtoPreCostNextHopInterface 1.0.0.0/8OSPF10210.0.0.1S3/0 2.0.0.0/8Direct002.0.0.2Eth0/1 2.0.0.2/32Direct00127.0.0.1InLoop0 10.0.0.0/8Direct0010.0.0.2S3/0 10.0.0.1/32Direct0010.0.0.1S3/0 10.0.0.2/32Direct00127.0.0.1InLoop0 20.0.0.0/8OSPF10230.0.0.3Eth0/0 OSPF10210.0.0.1S3/0 30.0.0.0/8Direct0030.0.0.2Eth0/0 30.0.0.2/32Direct00127.0.0.1InLoop0 127.0.0.0/8Direct00127.0.0.1InLoop0 127.0.0.1/32Direct00127.0.0.1InLoop0RouterC配置sysnameH3C # interfaceEthernet0/0 portlink-moderoute ipaddress30.0.0.32
