You have a source or a group member on R6's lan ? Below you said a member.
What does "sh ip igmp groups" says on R6 ?
The rpf failures are seen in the debug ip mpacket

Richard,
I have a source directly connected to the Lan interface on R6. I see the
packets arriving to the group member (it4s a router) and being forwarded by
R6, but after some minutes everything is stopped.
The unicast routing table don4t change and also the mpackets arrived to the
member. Anyway is there any debug to verify rpf failures?
Thank a lot for your help
Raul

Supposing that you have configured a joing-group on R6, I would start with
debug ip mpacket on R6, if nothing then go on to the next router until you
see why the packet is not forwarded. Have you checked rpf failures, seems a
prune has been sent though --Richard

Richar,
On R2, I have multiacces interfaces.
I have also tried with sparse mode and nbma mode, but the same behavior, the
traffic flows during a period of time.

On R2 do you have only one multiaccess interface or two subinterfaces ? If
only one multiaccess interface do you have sparse mode with nbma mode
configured ?

Subject: X - Proxy Join Timer Running - Multicast Flag
Group:
I have been searching without success in the group archive and in the cisco
web-site an example or explanation for the flag X - Proxy Join Timer
Running.
This is because in the following scenario with three routers: R2 (hub), R5
and R6 (spoken) with a source in (R5) and a group member in the LAN
interface of (R6), the multicast traffic just flows for a period of time and
then it4s pruned (I4m using mrm to generate traffic but I don4t stop it to
justify the prunning). I think the flag X could be the problem.
****************************************************************************

Traffic flow is OK
