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
