Multicast VPN issue

[gregwoodson]

I've got 2 core routers peered via BGP. I have deployed a Multicast VPN between them based on the following doc:

http://www.cisco.com/en/US/tech/tk828/tech_digest09186a00801a64a3.html

I actually see the multicast routes on all of the VRF's being broadcast from router to router and throughout the entire network. However, I am not able to see Multicast traffic passing. This is a very bizarre problem. Attached is the pertinent configs for the 2 routers.

Any ideas?

hi

Loopback 2 is using for customer auto-rp and it is in sparse mode and you are not using the ip pim auto-rp listner, so please do ip pim sparse-dense mode on the loopback 2. After that i think you will receive the stream. Becasue of sparse-mode your auto-rp for your customer is not flooding in the customer cloud that why you are not able to reveive the multicast stream. So please do it and let me knwo the outputs.

The first two pings of information came thru. Then the stream stopped. Is it possible that I need to manually designate an RP? How else can I test this at this point?

hi

Please check every interface should be using sparse-dense-mode.

Use the command

"show ip pim rp mapping" for rp information.
