/mcpshow ip rpf 10.1.1.1
RPF information for ? (10.1.1.1) RPF interface: Ethernet0/0 RPF neighbor: ? (0.0.0.0) - directly connected RPF route/mask: 10.1.1.1/24 RPF type: unicast (connected) RPF recursion count: 0 Doing distance-preferred lookups across tables
From the output, it is not an RPF issue. The RPF check correctly points out E0/0 to get to the source IP address. Check whether PIM is configured on the interfaces with the show ip pim interface command:
<#root> ROUTERA# show ip pim interface
Address Interface Version/Mode Nbr Query DR Count Intvl 10.1.1.2 Ethernet0/0 v2/Sparse-Dense 0 30 10.1.1.2 10.2.1.1 Ethernet0/1 v2/Sparse-Dense 2 30 10.2.1.2
The output looks good, so this is not the problem. Check whether the router recognizes any active traffic with the show ip mroute active command:
ROUTERA#show ip mroute active Active IP Multicast Sources - sending >= 4 kbps
Based on the output, the router does not recognize any active traffic.
<#root> ROUTERA# debug ip mpacket
IP multicast packets debugging is on
Perhaps the Receiver does not send any Internet Group Management Protocol (IGMP) reports (joins) for group 224.1.1.1. You can check it with the show ip igmp group command:
