Hi,
let me see if I understood right.
Spoke 1 is the RP and is also the router from where you want to ping
Spoke 2 is the router that is joining the group.
If yes, then I believe your problem may be the following.
When you ping out of Spoke1 the source ip address of your packet is going to be the serial interface ip address...
This will prevent Spoke1 from creating the proper (S,G) entry...i.e. the oif won't have the serial interface. I believe the code won't like to have Incoming interface equal to the Outgoing interface...
Try pinging using any other router address (remember to enable multicast on the interface from where you are getting the address)

Hi Aris,
Yes I can ping the address from the hub and spoke2, just not spoke1 to
spoke2.
When i so "show ip pim rp map" on Spoke1, it correctly shows itself as the
RP, but a sh ip mroute shows:
Spoke1#sh ip mroute

Why does it not show Ser2/0 in the outgoing interface list for
150.1.3.3,233.1.1.1?
Thanks,

Can you please join the spoke 1 or Hub ether or any other interface to this
group and then ping and check the result.
also please run the debup mpackets and check the output ,try checking the sh
ip pim rp-mappings command..

Hello everyone,
Please could you help me with a multicast problem I have. Here's the
topology:

Spoke1 Spoke2
I want to use a static RP (Spoke1 Lo0) for all groups, and join a group
(233.1.1.1) on Spoke2/Lo0. I do not want to use sub-interfaces on the serial
ints.
When I configure this, I cannot ping 233.1.1.1 from Spoke2.
Below are my configs:

Any ideas? I don't need a tunnel between spokes if I'm using nbma mode do i?
Many thanks,
