Hi Bruce,
Are you running ip pim sparse-mode on your serial interface? Also how are your
routers joining the RP via (static or dynamic mapping)? Here is a Cisco link th
at I ran across a while back. http://www.cisco.com/univercd/cc/td/doc/cisintwk/
intsolns/mcst_sol/frm_rlay.htm#47136
Let me know how this works out.
Thanx,
chris hugo

hought is meant, but it does not make sense as to why. The router that this deb
ug message came (R1) from has a loopback interface in this multicast group and
it also has a PIM neighbor (R2) on it's point to multipoint frame-relay serial
interface s1/0.123 and R2 also has a loopback in this group and a neighbor in
this group. I corrected the RPF issue with a static mroute and I am still rece
iving this message. There is another router connected to R1's multipoint interf
ace of (R3) which is not a multicast router. When I shut down R3's serial inter
face everything works fine so that leads me to believe that this non multicast
router is sending a prune message to R1 and therefore R1 is pruning that entire
multipoint interface. I added the PIM nbma-mode command and still no success.
Is there anything else that I can do.
