/mcpPossible Fixes You can either change the unicast routing table in order to satisfy this requirement or you can add a static mroute to force multicast to RPF out a particular interface, regardless of what the unicast routing table states. Add a static mroute:
<#root> ip22-72a(config)# ip mroute 10.1.1.1 255.255.255.255 10.2.1.1
This static mroute states that to get to the address 10.1.1.1 for RPF, use 10.2.1.1 as the next hop which is out interface E3/1.
<#root> ip22-72a# show ip rpf 10.1.1.1
RPF information for ? (10.1.1.1) RPF interface: Ethernet3/1 RPF neighbor: ? (10.2.1.1) RPF route/mask: 10.1.1.1/32 RPF type: static mroute RPF recursion count: 0 Doing distance-preferred lookups across tables
The output of show ip mroute and debug ip mpacket looks good, the number of sent packets in the show ip mroute count increases, and HostA receives packets.
<#root> ip22-72a# show ip mroute 224.1.1.1
