Hi Petr -
I tried what you mentioned and I did not get the info until I used the
deb ip pack detail. However, the response was not what I expected.....
*Mar 14 23:21:30.413: IP: s=45.1.1.4 (FastEthernet0/0),
d=255.255.255.255, len 80, rcvd 2
*Mar 14 23:21:30.413: UDP src=5000, dst=1967
I am not see the conversion.
I also check the basics and made sure that I did not have any RPF
failures and can ping the group at the other end. R5 is doing the B>M.
R1 is doing the M>B. At R5.....229.9.9.9 is the group being used for
conversion.

Subject: Re: Multicast Helper Verification
Dave,
you may try to enable "debug ip mpacket" and "debug ip packet detail"
on the
router that does the "M->B" conversion (as well as on the end router
that
converts "B->M"). For "debug ip packet" it's better to specify
access-list , e.g.
conf t
access-list 100 permit udp any any eq 5000
end
debug ip packet detail 100
Also, don't forget to configure the "receiving" side to actually receive
multicast,
e.g. with "ip igmp static-group".

I am looking to do the verification for the multicast helper
configuration. I believe the best way, is to set up the RTR application
using udpEcho on a router on the interface, then.... Using the debug on
the router to verify the broadcast to multicast conversion. However,
the debugs for ip mpacket do not provide the info. Has anyone been able
to do this successfully?
