Jai,
Because you using igmp snoopping, you also have to define multicast router
on the switch for it to be able to snoop.

Subject: RE: Multicast - Frame Relay problem
Hi
Thanx for ur response. We have enabled IGMP on the CAT6k switch. Also the
pim enabled routers are forming neighbour relations properly.Refering to
the diagram below
RF is able to ping the 224.3.3.3 address. From RA I am not able to ping the
224.3.3.3 address if the source ip address is the
Serial interface ip address. Now if I change the source ip address for the
ping from RA to the Ethernet ip address of RA then the ping is successful.
Basically on RC , with deb ip mpacket, its seen that for ping from RA with
source ip address of Serial interface there is no OIL list available .
This sounds strange but its left me confused. Any help in this matter is
appreciated.
Thx
JP

Jai,
Did you enable cgmp on switch and on the router interfaces. Why do you think
RD cannot be the RP. As for as I can see there is no reason for why it
cannot.

I was trying out some thing which is not working. Here it is -
RF
|
RA====FR Network =====RB
|
RC======RD=====RE
The above setup consists of FR network RC is hub. RA & RB are spoke.
RC, RD and RE are connected on Ethernet.
Requirement is to make RD as RP (Rendezvous Point). RE is joining the group
224.3.3.3 which should be accessible from all the routers.
I tried this but it would not work. I will be able to reach 224.3.3.3 from
RC and RD, but not from RA and RB.
If I check the mroute table on RC for RA and RB, I can see (*,G) entry with
proper RP entry. (S,G) entry will have proper incoming interface. But the
RPF nbr entry in (S,G) entry will point to RA/RB serial interface instead of
pointing to RD interface. Outgoing list will be empty.
I am able to reach 224.3.3.3 from RF without any problem.
If I make RC as RP everything works fine.
Is it possible to make RD as RP, if yes then what are the basic
requirements? If not then why ???
Thanks in advance.
Rgds
JP
