Dear GS,
I have Network Diagram :
R5 ---------- SW2 ------------- R1
R1 have to be multicast group for 224.0.0.0 -231.255.255.255 and R5 should
be multicast group for 232.0.0.0 - 239.255.255.255
SW2 act as the mapping agent
This multicast diagram have to in ip pim sparse-mode
In solution, I notice we have to use IP Pim auto-rp listener,
But before I look at the solution guide, I verify with show ip pim
rp-mapping and the mapping is works fine (I think)
So can you guys verify what happen if I do not use IP PIm autorp-listener.
Here ths show ip pim mapping before ip pim rp auto listener configured :
R1 :
