Dear Ryan, you are totally right. it seems i need some rest. I configured pim sparse on the ppp link of R2 (s 1/1) instead of serial 1/0. I read the interfaces config many times and i don't now how i didn't see it. In my mind it was that sparse was configured on the right interface.
Thank you once again for your thorough support. On Mon, May 6, 2013 at 4:52 PM, Bodnar, Edward <[email protected]>wrote: > Your only seeing 1/2 of your multicast tree.
