Sorry, R4 is the RP (instead of R3).
Now I understand that the first packet is encapsulated in unicast
register toward the RP and than switchover is done toward the tunnel
(assuming that a mroute static route has been added for mcast source
address, pointing to tunnel).
All right, thinks

Subject: Multicast Tunnel solution
Hi Experts,
I have this network:
mserver---------
Eth------------R4-----------DLCI103-------------R3------------DLCI302---
-----------R2--------Eth-----------RX224.2.2.2
R3 is the BSR RP for all multicast groups.
R3 is the HUB router with R4 and R2 as Spokes.
I am not allowed to use "ip pim nbma" command in R3.
So, I will use a GRE tunnel between R4 and R2 and activate pim sparse
mode in this tunnel.
My questions are:
1- how does this work?
2- Is the tunnel used after the swap from shared tree
to the source tree?
3- is there any other solution for this?
thanks in advance
