It's funny, I had the *exact* problem with bootcamp lab 20.  I
eventually got it to work but I had all sorts of problems.  I wasn't
able to get Auto-RP to work at all, for some reason, so I had to
manually define it.  Still, I really had some issues that irritated me
but they were so intermittent I wasn't able to nail them down.

For instance, toward the beginning of my configurations I was able to
ping the multicast address from R5.  I thought that was pretty cool so I
moved on to--IIRC--R1 and R3.  I couldn't get them to work so I went
back to R5 and discovered it could no longer ping the multicast
address.

One thing I kinda remember--someone please correct me if I'm wrong--is
that you need to have a single RP for the multicast group.  When I first
started the configuration, each subnet had an RP and that didn't seem to
work.  Specifically, on the R6--R13 subnet I didn't assign an RP at all,
which caused a problem.  Then I made R13 the RP and it still didn't
work.  Then I made R5 the RP for everyone and that seemed to resolve my
issue.

I really need to get cracking on this multicast stuff, though.  I feel
like I'm just scratching the surface.

I ran into the exact sma problem whilst doing bootcamp lab 20.  I ended
up
abandoning it but I will go back to it before next Friday (my date
with
destiny).  What I should ask you to check is do a ping 224.x.x.x or
whatever
the group was, then go to the router which has the igmp join group
command
on it and do a show ip mroute.  Check to see where the router see the
RPF
for the outgoing interface of the router you are trying to ping from. 
My
fuess is that it will be out of the wrong interface or something like
that. 
Also please ensure that you have the broadcast keyword after any frame
maps
you have in the process.

Cheers

Subject: Multicast over Frame relay [7:34098]


I am sorry to post same question second time over here. I didnt get
any
response to my earlier posting.

I am trying to do multicast over frame relay in Hub and Spoke topology.
I
am using IP PIM SPARSE mode with IP PIM NBMA MODE.  I have Hub as as
RP.
I have made one of the spoke, member of a IGMP group. I am trying to
PING
that group address from other spoke, but I am not getting any response.
I
am able to ping that group from Hub router.

Is there any thing else I need to configure to make it work ?

Thanks

Veerender Attri
