Re: PIM-SM Question - How to trigger a Join on demand.

Thank you Brian! I will def use this the next time the issue comes up.

I
also have listened to your Multicast bootcamp from INE twice now and wanted to
tell you that I think it is simply a great product. Thank you for creating
such
an indepth class. I'm a true fan :)

Best Regards,

David Serra

"clear ip mroute w.x.y.z"
will remove the state for the group, then using the
"ip igmp static w.x.y.z"
on your SVI down to the client's LAN should reinstate
the PIM join to
upstream.
