I would be useful if folks would include

As mentioned earlier, We're seeing no routes in inet.2 (multicast)
from Bradley. I pulled the AS off that last mail, and I see
everything from Bradley has the path 22335 32698 26367. So
address-family multicast in BGP needs to be checked between
Bradley and PeoriaNEXT, and PeoriaNEXT and MREN. After that's
running, we'll look at MSDP. Can someone give me a source
addr at Bradley for this multicast session and the group address?
Would also be nice to know the IP of an active receiver.
(I am wearing my Abilene hat here - I have no visibility
into MREN.)
Thanks,

If I had to guess MSDP isn't setup quite correctly. What RP addresss
are you using?

The RP must put the sources into MSDP and uses the RP address to
originate the MSDP messages, which must properly RFP check in
remote ASes.

Otherwise check with MREN, I remember something about the
Force10 having some kind of Multicast bug. I'm, not sure if it is still a
problem or if it was even related to these symptoms.

We are having problems with AccessGrid here. Our networking support has been unsuccessful in finding a solution thus far.



We ARE able to see and hear remote sites but they AREN'T able to see or hear us. Of course, when we switch to unicast the promlems go away...

We are able to conference amongst each other on our campus but anything going out doesn't get thru.

We are going to start troubleshooting this at 8am. If you could provide us some assistance that would be great. Let us know regardless.

Thanks
Cory Rabe
